Hot For Teacher - one of the quintessential Van Halen songs. It is the 80's condensed into one ass kicking of a song. Over the top video? Check? Lyrical content contains references to drinking, partying, or banging hot chicks? Check. Guitar solo badassery? Check. DLR being DLR? Check. Man, this song is unreal. Just turning it on, grabbing a guitar, and playing along makes you feel better. As Roth said, "'Old Van Halen, when I was in it-classic Van Halen-makes you wanna drink, dance and screw, right? And the new Van Halen encourages you to drink milk, drive a Nissan and have a relationship." As much as I like Sammy, I can't deny that old VH has that effect.
WLAE - Nice. It's a pretty catchy tune and it didn't hurt that even the least hot Bangle was still hittable. I hear it from time to time and am still shaken by that guitar tone at the end, the big brassy Danelectro-ish kinda sound. Cool. Still an earworm of a tune. As for Susanna Hoffs, if you haven't seen it, look up her live cover of Bad Company's "Feel Like Makin' Love" and attempt to not be stirred by it.
EDIT: Saw the additional comments and thought "I really liked Eternal Flame." Then saw KS mentioned it.
EDIT #2: If interested (hint: you're interested), here's the aforementioned Susana Hoffs "FLML" performance.
