1st vote: Queen
2nd vote: The Beatles
Queen. Literally. Influenced. Everyone. If you check through a list of all of your favorite bands of every genre, at least half list queen as an influence. Songs like "Bohemian Rhapsody" and "We Will Rock You/We Are the Champions" have endured the test of time, and always will.
The Beatles for basically the same reason. Without them, Guitar is history. What is Rock without guitar? What is drums without guitar? What is Bass without guitar? What is... MUSIC... WITHOUT GUITAR? Scary thought...
I'm not the biggest fan of the Beatles MUSIC though, it's still good by the way. I've always found The 'Stones overrated (FLAME SHIELD ACTIVATED), and have never been familiar with CCR, The Doors, or Golden Earring.
I know and respect Jimi's legacy AND Guitar Mastery (I talk too much about guitar for a drummer^.^), but I could never really get in to his music though. Foxey lady is good though, and it being in one of the funniest scenes in Wayne's World doesn't hurt eather.
Overall, Queen wins this round.
