AI song generator for finished tracks from ideas or lyrics

SoundUser has 3 input modes: describe an idea, paste your own lyrics, or make an instrumental track. Use the idea mode when you know the mood but not the words. Write something like late-night synth pop about missing the last train, 104 BPM, A minor, female vocal, gated drums.

Paste lyrics when the hook or story matters. Keep verse, chorus, and bridge labels in the text so the AI can follow the form. If your chorus is the payoff, label it clearly instead of hoping the model guesses.

Choose instrumental when vocals would get in the way. This works for background beds, intro music, ambient loops, guitar cues, piano sketches, and beat ideas. If that is your main goal, the instrumental music generator page gives tighter prompt patterns for non-vocal tracks.

You can make a song with AI in 3 steps, and each step changes the final track more than a long paragraph of mood words.

1. Write the job. Say what the song is: a breakup ballad, a drill beat with a sung hook, a birthday folk song, a piano instrumental for a video intro.
2. Pick the production frame. Add BPM, key, vocal type, drums, bass, main instruments, and era. 92 BPM, A minor, punchy kick, vinyl texture gives the model firmer rails than cool hip hop song.
3. Generate and revise the prompt. If the first take misses, change one thing first: tempo, vocal, density, or genre. Big rewrites can fix the wrong problem.

For a focused lyric workflow, start with text to song. If you want a broader tool overview, see the AI music generator page.

A strong first prompt needs 5 things: genre, tempo, key, instruments, and vocal direction. Most weak prompts fail because they describe a feeling but not a record.

Weak prompt: sad song about rain.

Better prompt: indie synth pop, 104 BPM, A minor, wistful song about rain on a night bus, analog synth arpeggios, gated reverb drums, jangly clean electric guitar, warm female vocal, chorus opens up with stacked harmonies.

That prompt is meant to produce a mid-tempo pop track with a clear pulse, minor-key color, and a chorus that feels wider than the verse. If the result gets too glossy, add dry verse vocal, less bright synth, smaller chorus drums. If it drags, raise the BPM or change the drum note to four-on-the-floor kick. If the vocal over-sings, ask for plain close vocal, no melisma.

For more prompt patterns, use the prompt writing guides before you spend extra runs chasing vague fixes.

Lyria 3.5 returns a finished track that runs up to 180 seconds. Treat it like a complete AI recording, not a stem pack or a MIDI export. Your prompt controls the likely arrangement: drums, bass, harmonic instruments, lead parts, vocal presence, and overall mix style.

A track costs 10 credits. SoundUser is built around paying per track, so you do not need to judge value through a large bundle or a subscription comparison before making one song. One generation creates one track from the prompt and settings you choose.

The practical move is to spend the first run on structure, not tiny mix notes. Get the genre, vocal, tempo, and lyric format right. Then use the next prompt to fix the biggest miss. Less hi-hat, warmer bass, chorus arrives sooner is a better revision than ten new adjectives.

Choose your next page by 4 intents: style, lyrics, occasion, or usage question. This home page is the hub, but the more specific pages give better prompt angles.

If you are not sure, pick the page closest to the hardest part. Style problems need genre help. Weak words need lyric help. Personal songs need better names, places, dates, and details.

Use 2 rules for vocals: write the language you want sung, and label the song parts. The model can follow plain lyric structure better when you mark [Verse], [Chorus], and [Bridge]. Do not paste a wall of text and expect a clean pop form.

For vocal tone, use singer direction instead of famous names. Write soft male vocal, raspy alto, spoken rap verse, or close female lead with light doubles. Real artist names are the wrong shortcut and can push the prompt away from the production details that matter.

For instrumentals, remove vocal words from the prompt. Do not write catchy chorus if you want no singing. Write lead piano motif returns after the bridge, 808 bass carries the hook section, or muted guitar melody replaces the vocal. A good instrumental prompt still has sections. It just assigns the hook to an instrument instead of a voice.

Most bad first generations come from 4 fixable prompt problems: vague genre, crowded instruments, missing tempo, and unclear vocals. Fix one at a time.

If the song sounds like the wrong genre, add a tighter style tag and rhythm section: boom bap, 92 BPM, chopped soul sample, punchy snare is stronger than old school. If the mix feels busy, remove instruments. Acoustic guitar, upright bass, brushed drums leaves more space than a list with piano, strings, synths, choir, and percussion.

If the hook feels flat, tell the arrangement what changes: chorus adds higher bass notes and harmony vocal, or drop drums for first half of chorus, then full kit returns. If pronunciation matters, simplify the line. AI vocals handle direct phrasing better than tongue-twisters, dense alliteration, and bracket notes inside a sung line. Small edits beat starting over.
