Decentralized music just means the artist maintains control of their RSS feed so they never lose custody of their art and listeners can support them directly (if they so choose). You can find free hosting for your XML file if needed and it only takes a few minutes to build using tools like MusicSideProject.com
But then, that RSS feed can be shared in MANY places (easiest of all the new podcast apps via the Podcast Index) and tracks can be shared to ANY mainstream platform the artist desires. Then when censorship strikes or rugs get pulled, the artist still truly owns their art and fans have been able to send them value directly the whole time.
The first proof of work for DeMu was the Stay Awhile album from Able and The Wolf, published Christmas Eve of 2021, so the concept is only 4 years old. But the artists in those value splits are STILL receiving value without issues (me included.) Live concerts are decentralized now too since the first Satellite Skirmish paved the way! The space has been growing steadily and will continue to do so.
I'm always happy to fight the FUD for anyone interested in learning. 💜
