I just wish google music had a desktop client (or support in chrome) to hook into operating system keyboard shortcuts like play, pause, forward, next, etc.
I just found Sway.fm for Chrome last night, and it's been awesome for playing SoundCloud.
Ah, yes forgot about this. Play music doesn't allow you to save your music for offline listening on your laptop (windows/osx). Which sucka, but wasn't a problem for me, because I always listen on my phone/tablet,
