Frequently Asked Questions

You describe what you want (the occasion, the person, the vibe, any memories you want the song to capture) and our AI assistant builds a professional music prompt from your story. That prompt gets sent to a state-of-the-art music generation model that produces a full song with real-sounding vocals and instrumentation. The whole process takes under five minutes. You can generate songs free and sign up to download and keep them.

None at all. You don't need to know what a key signature is, what BPM means, or how to describe chord progressions. If you can tell a story ('my wife loves country music and we met at a honky-tonk in Nashville') the AI handles the rest. The assistant asks smart follow-up questions to fill in any gaps, so you always have a guide if you're not sure where to start.

Yes. Sign up free, no credit card, and you get 1 free song credit just for joining, enough to create your first full song and hear it with real vocals and instrumentation. If you love it (and we think you will), a single song is just $1, or grab a 5-pack for $4.50. Credits never expire, and there's no credit card until you decide to buy.

Songs typically generate in 60 to 90 seconds. You can queue a generation and come back, we'll have it ready. The AI assistant interview itself takes about 2-3 minutes if you want the guided experience, or you can skip it and type a prompt directly.

The short answer: almost anything. Country, pop, R&B, hip-hop, rock, folk, acoustic, lo-fi, classical, jazz, electronic, gospel, metal, reggae, blues, and more. You can get specific about sub-genres too (southern rock, dream pop, bedroom pop, trap soul, Americana, indie folk, synthwave, cinematic orchestral). The more specific you are, the more dialed-in the result. If the AI doesn't nail it on the first try, a prompt tweak usually gets you there.

Yes. Every generation has a vocals/instrumental toggle. Instrumental tracks are great for background music, video content, meditation, studying, or when you just want the melody without lyrics. You can also mix: request that lyrics are present but subtle, or ask for a specific vocal style (whispered, soaring, conversational).

The key is specificity in your prompt. Instead of 'happy pop song,' try 'upbeat, driving pop with punchy drums, bright synths, and a female vocalist with a warm mid-range voice, think early 2010s radio pop, energetic but not aggressive.' Reference the feel of an era, the instruments you imagine, the emotional energy. Our AI assistant will ask you these questions if you use the guided mode. You can also regenerate multiple times from the same prompt, the results vary, so sometimes you get it right on the second try.

The AI writes them for you. Tell it about the song (the names, the relationship, the memories, the occasion) and it writes original lyrics built around your story, with structure like verses, a chorus, and a bridge. The more detail you share, the more personal the result. You can keep refining with the assistant until the words feel right, then generate.

Absolutely. Our song creation assistant can workshop lyrics with you collaboratively. Just tell it about the song you want, and it'll help you craft verses, a chorus, and a bridge. You can go back and forth until the lyrics feel right, then generate the song.

Yes. Every track in your library has a remix button that reopens the assistant with your original prompt loaded. You can adjust the style, tweak the lyrics, change the mood, then generate a fresh version. Your original stays untouched.

You own every song you create with SonicStacker. Personal use is included with all plans: share it at a party, post it on social, give it as a gift. Commercial use (for ads, monetized content, client work, sync licensing) is at your own discretion and risk. AI-generated music may not qualify for copyright protection in all jurisdictions, so we recommend independent legal review for commercial projects. If you're unsure, reach out and we'll give you a straight answer.

You do. Songs you generate are yours to use within the license tier you've purchased. We don't claim any ownership over the output, we don't license your songs to other users, and we don't use your songs for anything other than delivering them to you. The full details are in our Terms of Service, but the short version is: what you make is yours.

Nothing, they never expire. Any credits you buy stay in your account until you use them, with no monthly reset and no deadline. Your finished songs are yours forever too.

Tweak the prompt and regenerate. And every $1 Single comes with our Perfect Song Guarantee: if your song genuinely misses the mark, contact us and we'll credit you another one. Our goal is that you end up with something you're proud of, not a shrug and a refund request.

Most AI music tools give you a text box and hope for the best. SonicStacker has a conversational assistant that interviews you about the song before generating anything: occasion, memories, emotional tone, specific details. The result sounds intentional, not random. We also write original lyrics from your story, offer a remix feature to iterate on songs, and a library system so your songs are organized and accessible. We're built specifically for personal and gifting use cases, not generic background music.

Every song is generated fresh from your specific prompt, it's not pulled from a library or remixed from existing tracks. Our AI music engine creates original audio from scratch based on your text description. No two songs are identical, even from the same prompt. The instrumentation, melody, vocals, and arrangement are all generated in real-time for your request.
