Just in answering the poll (for now) and I'm going with 6 because I can't narrow down to only 5:
#1 and it's not even close ... Bohemian Rhapsody ~ Queen
Rocky Mountain Way ~ Joe Walsh
Hotel California ~ Eagles
Takin' Care of Business ~ BTO
Brown Eyed Girl ~ Van Morrison
Born To Be Wild ~ Steppenwolf
Interestingly enough, they just played BTO for the 2nd time that I've heard today, and I've only been listening for a couple of hrs. As for Queen, I'd like to thank Mike Myers and classic rock radio for completely ruining this song for me. I really used to like it, but I can say with conviction, if I never ever heard Bohemian Rhapsody ever again in my life, I'd be just fine with that. Honestly, I think I could say that about all of the other 5 as well, especially the last 2 (being Van Morrison and Steppenwolf)
