under pressure by queen changes tunes like 3 times... no song does that. normally a song has one tone with the same lyrics repeating but this bad motherfucker it's like a whole album in one! :)
You can pretty much thank John Deacon for that song. It was him who wrote that iconic riff that was so blatantly stolen by Vanilla Ice.
Like Scott mentioned, if that's something that appeals to you then you should definitely look into the prog rock genre.
