But the thread is for "greatest song" of all time. If it were "greatest band", you'd be on target. However, I will say that - from Come Together - "got to be good looking cuz he's so hard to see" is my favorite pop music lyric of all time. As for greatest song, I'm going to go with "American Pie."
I think it speaks to the strengths of the bands. Queen made ho hum albums with a great song here and there. The Beatles made great albums.
