Just installed Headset on my work PC. Will install at home later (and, in fact, I may setup my old laptop as a sort of lazy person's media centre, connected to my stereo so I can run it that way).
At least until YouTube changes the API settings, this is a pretty killer music stream "service." It's got a huge and de facto free library, no ads...it's pretty snazzy the way they've implemented this thing. (On the other hand, I think it's an Electron app and I know a lot of people hate that shit.)
