AmpMe is a make-shift surround speaker system on your devices. It turns all of your phones and tablets (and your friends’ phones and tablets) into speakers for the same song, synchronizes playback across all of them, and lets the party starter choose which tracks get streamed for everyone. When it was released in October, I reviewed the app and concluded that it was good, but that it was neck-to-neck with SoundSeeder, another alternative on Android.
