The title says it all. Audius is a quite promising new streaming service. I’m not sure how relevant the whole basis on a blockchain is, and what real world problems it’s realistically solving, but the fact is that for now it’s the only service I know of where an artist can get his or her music streamed in high quality 320kbps for free, without any upload time limits.
I have uploaded most of my released music there already, enjoy!
