This is an app that let's you listen to your Android's Music and control it with the proximity sensor... mmmm Why??
·You are cooking (dirty hands)
·You are in a car driving (it's very fast change the song with de proximity sensor)
·You can control it with the screen off (while you are working, studying, no need to distract: unlock phone, search a song...)
·You are making some kind of sport, and don't want to stop just for select the next song
·You have another app open (Maps, facebook...) and you don't want to close it just for go to the next song
·Just for fun :)
