I'm currently looking into this for streaming (twitch in particular) specifically. A musician can license their music within the Creative Commons. This means that people can do almost whatever they want, use it wherever, remix it, etc... As long as the author gets attribution. Similarly, specifically for streaming, you would need a _synchronization license_, the license required to synchronize music to image (ie, streams). It is possible to issue a global blanket sync license, meaning that basically everyone can use it, usually with the same requirement that you the streamer give attribution
