You pasted 200 words of lyrics and Suno sang something completely different. The model is not “improvising” for fun. In almost every case it treated your text as a theme description rather than lyrics to sing, because you were in the wrong mode. Suno’s Custom mode sings the words in the Lyrics box; the default (Simple) prompt box treats whatever you type as a brief and writes its own words. As of June 2026 (Suno v5.5), the great majority of “lyrics ignored” reports come down to the wrong mode or missing structure tags.
Fastest fix: turn on the Custom toggle (top-right of the Create panel), paste your words into the Lyrics box only, and wrap each section in bracket tags like [Verse 1] and [Chorus]. That alone solves most cases. If a specific section still gets dropped, trim your lyrics to fit the song length and use Replace Section to force it.
Which bucket are you in?
| Symptom | Most likely cause | Jump to |
|---|---|---|
| Suno wrote totally different words | You are in Simple mode, not Custom | Step 1 |
| Right words, wrong order / chorus sung as verse | No [Verse] / [Chorus] tags | Step 2 |
| First half sung, rest dropped | Too many lines for the song length | Step 3 |
| Barely any vocals, mostly music | Styles field implies instrumental | Step 4 |
| Random lines skipped or garbled | Emoji / markdown / HTML in lyrics | Step 5 |
| One section (e.g. bridge) always skipped | Section-level miss | Step 6 |
Common causes
Ordered by how often each one drops the lyrics.
1. Default (Simple) mode instead of Custom
Suno has two ways to create:
- Simple (default prompt box): you type a description (
a happy song about coffee), and Suno writes the lyrics, style, and structure for you. - Custom: you supply your own lyrics plus a
Stylesdescription, and Suno sings the words you gave it.
If you paste finished lyrics into the default prompt box, Suno reads them as a theme and rewrites everything.
How to check: is the Custom toggle at the top-right of the Create panel switched on? If it is off, you are in Simple mode and your lyrics are being used as a prompt.
2. No [Verse] / [Chorus] structure tags
Even in Custom mode, plain-text lyrics with no tags let the model segment the song its own way from line breaks alone. Common result: the chorus you wrote gets sung as a verse, your verse becomes a bridge, and lines get reordered.
How to check: do your lyrics include [Verse] / [Chorus] / [Bridge] bracket tags, each on its own line? If not, this is your problem.
3. Lyric count doesn’t match song length
Suno tends toward 2-3 minute songs unless you push longer. A rough line budget:
| Length | Line count (English / Chinese) |
|---|---|
| 1 min | 12-16 / 8-12 |
| 2 min | 24-32 / 18-24 |
| 3 min | 36-48 / 28-36 |
| 4 min | 50-65 / 40-50 |
Put 100 lines into a 2-minute song and the model has to pick a subset; the rest get dropped.
How to check: lines per minute above ~32 (EN) or ~25 (ZH) means you have too many words for the length.
Note: as of June 2026 the Lyrics box accepts up to 3,000 characters, so the limit you hit first is usually song length, not the field.
4. The Styles field describes a vocal-less arrangement
Words like instrumental, background music, or lo-fi beats hint “no vocals or sparse vocals,” so the model may hum a few lines and skip the rest. (Separately, if the Instrumental toggle is on, Suno produces no vocals at all — check that it is off.)
How to check: does your Styles text contain instrumental / no vocals / background music, or is the Instrumental toggle on?
5. Special characters / emoji in lyrics
💔, <3, emoji, and stray markdown symbols get filtered as non-lyric text and can throw off the lines around them.
6. A Persona or voice whose style doesn’t fit your meter
If you apply a rap-trained Persona to a slow ballad (or vice versa), phrasing gets forced into the wrong cadence and the words come out mangled, even though they are technically all there.
Shortest path to fix
Ordered by lyric-hit rate.
Step 1: Turn on Custom
In the Create panel, switch on the Custom toggle (top-right). You now get separate fields:
- Lyrics (your words go here)
- Styles (genre, tempo, mood, instruments, vocal type)
- Title
Put lyrics in the Lyrics box only. Never paste them into Styles. Make sure the Instrumental toggle is off, or you will get no vocals.
Step 2: Add structure tags
Rewrite your lyrics with a bracket tag on its own line before each section:
[Verse 1]
I opened that old album
You were laughing on the first page
Outside the rain fell and stopped
Like the promise we never finished
[Pre-Chorus]
Late at night I'm still awake
[Chorus]
Turns out you'd already left
What's left is just the echo
Turns out you'd already left
And I'm learning to be alone
[Verse 2]
...
[Bridge]
...
[Chorus]
...
[Outro]
Turns out you'd already leftConfirmed-working tags (each on its own line):
[Intro],[Outro],[End][Verse 1],[Verse 2][Pre-Chorus],[Chorus],[Post-Chorus][Bridge],[Hook][Instrumental],[Instrumental Break],[Guitar Solo](no vocals in that section)[Spoken Word],[Whisper],[Male Vocal],[Female Vocal]
Two reliability notes from real use as of June 2026: [Intro] is the least reliable tag (Suno often ignores it), and Suno does not consistently honor (x2) or (repeat). If you want the chorus sung twice, write the full chorus lines out twice under the [Chorus] tag.
Step 3: Match line count to song length
Trim or extend your lyrics to the budget in the table above:
- 2-min song: 24-32 EN lines
- 3-min song: 36-48 EN lines
Over 50 lines? Split the song into two parts (part 1 / part 2) or push the length out — v5.5 generations can run up to 8 minutes, and you can keep going with Extend.
Step 4: Don’t write a vocal-less Styles field
Avoid:
instrumental, background music, lo-fi beatsWrite instead (the field holds up to ~200 characters; keep it to roughly 4-8 comma-separated descriptors):
85 BPM, indie pop, soft female vocal, melancholic, fingerpicked guitarNaming a vocal explicitly (female vocal, male vocal) tells the model the lyrics are meant to be sung.
Step 5: Strip special characters
Remove from the lyrics:
- All emoji (
💔,🎵) - Markdown symbols (
**bold**,*italic*) - HTML (
<br>,&) - Runs of blank lines (don’t leave 3+ empty lines in a row)
Keep: normal punctuation, single line breaks, and [Section Tags].
Step 6: Still skipped? Force it with Replace Section
If one section (often the bridge) keeps getting dropped:
- Open the finished track in the editor and select the time range for that section.
- Choose Replace Section (this is Suno’s inpainting tool).
- In the input, paste only that section’s lyrics with an explicit tag, e.g.
[Bridge], then regenerate.
Replacement is iterative — the first pass rarely blends perfectly with the surrounding bars, so expect to regenerate the range a couple of times.
How to confirm it’s fixed
- The Custom toggle is on and your words appear in the Lyrics box (not
Styles). - Play the result with the lyrics panel open: every
[Section]you wrote is sung, in order. - If you wrote a chorus to repeat, it recurs the number of times you wrote it out.
- No long stretches of pure instrumental where you expected vocals (if there are, recheck Step 4 and the Instrumental toggle).
FAQ
Why does Suno write its own lyrics when I paste mine? You are in the default (Simple) prompt box, which treats your text as a theme. Turn on Custom and paste the words into the Lyrics box; Suno then sings them.
Does Suno follow my lyrics exactly, word for word? In Custom mode it sings the words you provide, but melody-to-line mapping is not perfectly deterministic — phrasing and emphasis can vary between generations. Structure tags make section order reliable; if a line is consistently dropped, it is usually a length or special-character problem.
What is the lyrics character limit in 2026?
As of June 2026 (v5.5) the Lyrics box accepts about 3,000 characters and the Styles field about 200. Hitting the line-budget limit for your song length is far more common than hitting the character cap.
Why does my chorus only get sung once when I marked it (x2)?
Suno does not reliably interpret (x2) or (repeat). Physically write the chorus lines out as many times as you want them sung, under repeated [Chorus] tags.
Suno skips my intro even with [Intro] — is that a bug?
No. [Intro] is the least reliably honored structure tag. Either accept it or put a short instrumental cue like [Instrumental Intro] and move your opening words to [Verse 1].
My lyrics are all there but sound mangled. What now?
Check whether you applied a Persona or voice whose style (e.g. rap) fights your meter, and confirm there are no emoji or markdown symbols breaking the lines. Try regenerating with a Styles field that names the intended vocal.
Prevention
- Always use Custom mode; the default prompt box is for “play me something random.”
- Add
[Verse]/[Chorus]tags even on short tracks, each on its own line. - Match line count to length: 2 min ≈ 28 EN lines, 3 min ≈ 42 EN lines.
- Keep
Stylesshort (4-8 descriptors) and name avocal, or it may default toward instrumental. - Strip all emoji / markdown / HTML from the lyrics.
