Get back to business and leave the entertainment of the world to the XBox team guys.
My old Casio SK-8 keyboard did a way better job at accompaniment. Plus it could playback belches in different octaves. And it had that gunshot and ricochet sample.
The Metallica track does sound better than some of their more recent stuff, though.
Should have plugged some Soundfonts into the app instead of the cheesy 80s MIDI samples.
Everything needs more cowbell too.
