This is tough.
Category 1: Solid, but not great, JP song; good, but not great, Leppard song; crappy Crue song.
Category 2: Good, but overrated, Metallica song; solid Scorps song; one of only 2-3 Dokken songs worth a damn.
Category 3: Great QR song (best song in the poll) teamed up with crap and Ratt.
Category 4: All three are solid, but nothing exceptional.
Category 5: Another solid grouping, but nothing exceptional.
3 is out because the garbage GnR track and the mediocre Ratt song cancel out the QR song, and 1 is out because of the Crue track. I guess if you told me I could only listen to one of the remaining groupings, I'd pick 2, so there it is.
