No one song in particular, but I really wish I could hear these albums again for the first time, as each one blew me away on the first spin. It wasn't just one song or two, but the entire albums:
Kiss - Alive! (1975)
Kiss - Creatures of the Night (1982)
Dokken - Tooth and Nail (1984)
Ozzy Osbourne - Bark at the Moon (1983)
Triumph - Thunder Seven (1984)
Tesla - Mechanical Resonance (1986)
Guns n' Roses - Appetite for Destruction (1987)
There are a lot more, but I've already kind of gone a bit off topic.
