Broadcasters on Twitch gained access to another source for music Thursday. The gaming platform, which Amazon acquired in August 2014, introduced music.twitch.tv, a library of free-to-use music that Twitch broadcasters will offer up for live content and associated archived video. The Twitch Music Library features more than five hundred songs from established and fledging labels, including Mad Decent, Dim Mak, Spinnin Records, OWSLA, Monstercat, and Fools Gold. The site said it will continue to add to this library as more music industry partners become part of the system. It is also experimenting with music content creators with a new beta Music category.
