Literally don’t even know where to start here. How about this: this was Prince’s signature song. Sure, he had bigger singles (and in fact, cutting the “Purple Rain” down to 4:05 for its single was as stupid as when The Who cut “Won’t Get Fooled Again” down to 3:36, I mean why even bother?), but I don’t think he had a bigger song. On every level.
I mean, you could imagine going to a Prince concert and not seeing any other song, but going to a Prince concert and not seeing “Purple Rain” seems totally unimaginable.
