I like the way that you can turn your PC to youtube tv/player by going to https://www.youtube.com/tv#/browse and pair it with an Android phone. Then, android app can play videos in this Chrome tab.
I want to do the same with my music stored in Google Music (music.google.com). I want to control the playlist from my phone and but I want the PC with speakers to play the actual sound. See the youtube.com/tv - you can search and select the clip on the phone, but it will play in the PC browser remotely.
Is it possible to do this? Some site or some Chrome extension?
