Kevin Macleod. I've seen his music used all over the place. Royalty free, published under the Creative Commons license. His website even states that you're free to use it as long as you credit him. Hundreds of songs available in all sorts of genres. Problem solved.
Well, I mostly meant like, ingame music? If Twitch is chopping people because of that then there's no helping'em. As for remix's there are plenty of services that aren't shit that offer good shit. OCremix comes to mind, and lots of people on Soundcloud and Bandcamp.
there are millions of noncopy right music out there. They should just ignore the past clips and focus on the future and start fresh. Cant believe in our current year people still want to drown in a glass of water.
Either way I don't care what happens to moneywhore twitch streamers, if they cared about their streams quality over profitability they would have left to the many other alternative websites that are less abusive and predatory.
