Amp me App on Google play (also on App store) . A free app that lets you play the same song on multiple devices (on the same network). I Love this new app as I can connect up and sync my tablet, phone and Android box to play the same song simultaneously and through my various Bluetooth speakers connected to each device. Great for a surround sound music feel or listening to your music around the whole of your house as you move from room to room (like a very expensive networked sound system you could purchase instead!). Give it a go.
