I'm Welelo, a 46-year-old rapper from Spain who never quite made it — and refuses to quit. A few weeks ago I stumbled upon previewmychannel.com and it blew my mind. I started digging into who built it, found Fernando Pessagno, and spent a weekend going through everything he'd made. That was the spark. I'm not a developer. I build everything with Claude. And in the last few weeks I've shipped this free tool for independent musicians: 🎵 PreviewMyMusic — Simulate how your single will look on Spotify before you release it. Artwork, artist name, track info. No signup. https://previewmymusic.netlify.app It is free, client-side only, no backend, no data stored. I reached out to Fernando on X, he wished me luck. Small thing, but it meant a lot. I'm still figuring out what to build next. If you're a musician or know musicians, I'd love honest feedback — not from friends who are being polite, but from strangers who'll just close the tab if it's useless. What would you actually use?
