Two-Four Tuesday (v.1)

Here's a fun activity I'm giving our readers every Tuesday. Hopefully the appealing lure of this game will actually FORCE you to comment on this post! Welcome to the 1st edition of "Two-Four Tuesday"!

I will post the "Top Five" items in a list, except that I'm leaving out the 2nd and the 4th items. Your mission -- comment with your guesses (or "answers", if you're that confident) as to what the missing items are.

Since this is the pilot test of this game, I'm picking a more universal topic -- music. That should make it fairly easy for you to at least attempt some educated guesses. Don't cheat by looking up the info on the web -- just have fun and take your own guess. I'll give the correct answers the following Tuesday.
