Play music FROM (not on) multiple devices to just one. Is there any app (not speakerfy, seedio etc)? Chromecast can do it?
The Chromecast is a good app that you can use to play music into your TV. You need to plug it into your HDTV and control it with your laptop, smartphone or tablet. You can get more details about this app from https://play.google.com/store/apps/details?id=com.google.android.apps.chromecast.app&hl=en.
