There is a Bluetooth device that runs on an Android device. It is
the Mega Midi or Mini Midi sequencer from Brotech Electronics:

The system is an application that works on Android systems and
a "receiver" that you put in your instrument.  I have this system
and it is really wonderful.  It comes with an Android tablet, but if
you have an Android device, I don't think you have to buy the tablet.
The application allows you to select any song to play.
