Three pretty major tracks, obviously. But I’ll take upmixes if that’s the only way to get the other 12 in true surround. .
I've always imagined that a surround mix of "Senses Working Overtime" would have the "1,2,3,4,5" refrain before the chorus pop up in each speaker. Maybe a little gimmicky for SW, but we do have five speakers! Would probably be tough to do that in an upmix.
