That question would put my mind into total gridlock since I can't seem to make a grocery list let alone rank my favorite music. A poll to name the Greatest Riff of All Time puts "Voodoo Child" from Jimi Hendrix at Number 1.

2- Sweet Child O' Mine- Guns N' Roses

3- Whole Lotta Love- Led Zeppelin

4- Smoke on the Water- Deep Purple

5- Layla- Derek and the Dominos

You can see the full 50 here. Some had me scratching my head wondering just who participated in this poll, some had me playing the air in agreement. Have fun checking it out, I have to try to stop humming waah wah wah wah wah wahwahwah waaaaaaah wah wah waah long enough to remember what I need to pick up at the grocery store.
