i thought that harry styles' 'sign of the times' sounded a bit like sinead o'connor's version of 'nothing compares 2 u', so i downloaded and i guess i was right.
all i've done here is:
1) pan one song to the left and the other to the right
2) moved 'nothing compares...' so that both of the first verses start at the same time.
3) turned harry's one down a little bit to try and match the volumes.
other than that i haven't used any processing. they just match.
not really trying to make a point by doing this, just thought it was interesting.
