You could save the stream to a temporary (mp3) file and then play this file with MediaPlayer

EDIT to address comment:
The file would not be persistent, something like

File temp = File.createTempFile("whatever", "mp3", getCacheDir());
temp.deleteOnExit();
FileOutputStream fStream = new FileOutputStream(temp);
fStream.write(passYourStream);
fStream.close(); 
FileInputStream fStream2 = new FileInputStream(temp);
yourMediaPlayerInstance.setDataSource(fStream2.getFD());
