The Mac is a good one but I don't buy into this 'the whole band wrote it' thing. Lindsey wrote The Chain, the others probably prosed some lines and ideas, and maybe John McVie was in the room at the time. I'm only interested in self-contained bands, as in not a Steely Dan thing where its a couple dudes and session musicians, and songs that are only credited to one person. Queen really was pretty unique this way.
