How do you listen to your music when not using head/earphones?

I'm an avid google music user but find solutions a little disappointing.

Is there a way i'm missing of an android equivalent to airplay/chromecast but just for music, that also supports google music.

I 've tried sonos but the app was really annoying after a while and they had no google music support.
