Tons of great inclusions in this thread. And I'm surprised no Elton John but he's pop more than rock and I'm glad we've been more or less sticking to the latter.
Anyway.
I'll round out my very unofficial top 10 with #8, #9, and #10 as contributed by you fine members:
#8 New Year's Day - U2
#9 Foreplay/Long Time - Boston
#10 The Final Countdown - Europe
