You may be interested in https://v4vmusic.com It's a music app that's solely dedicated to music released on RSS feeds by mostly independent artists. It has nearly 27,000 songs in it. Tons of good stuff (tons of garbage also 🙂)

You can even support the artist's directly with bitcoin (At the moment only the alby and coinos wallets work 🙁)

The site is a work in progress so if you have any issues with it, feedback is always welcome (and needed)
