Show HN: Built an AI Song Creator with stem separation and commercial rights

Hey HN, I built an AI music generation platform that solves a problem I had as a content creator: finding royalty-free music that's actually usable. Key features: • Generate songs up to 8 minutes (vs typical 2-4 min limits) • Multiple AI models: lyrics generation, vocal removal, stem separation • Commercial license included - safe for YouTube, Spotify, TikTok • Export in WAV/MP3 with studio quality Technical stack: Next.js 15, multiple AI providers (DeepSeek, OpenAI, etc.), PostgreSQL, Stripe for licensing. Free tier available with 2 songs/month. Would love feedback from the community.
