The Internet is a fantastic medium for distribution, but copyrights get little murky. Just look at what's going on with Twitch and their on-again-off-again DMCA takedowns of streamers who play copyrighted music. It's insanely frustrating and can bring a streamer's revenue to zero quickly if they're "DMCA'd."
I'd love to see the DMCA repealed and rewritten. It's a cluster.
They have their own producers and just put it out there. Also, heard some Rock artists that mixed things up with an original sound.
