In my opinion, AC/DC is my second favorite band, right after Lynryd Skynyrd. Sure, the subject matter of their songs is pretty much limited to women, alchohol, partying, drugs, sex, cars and rock n' roll. But that's a combination that, at least to me, never gets old.
Angus Young is a guitar GOD. Every single solo of his makes me wanna bust out the air guitar, no matter where I am. That man can play!
Back in Black is still my favorite album of all time. Whenever I take a long trip, that's the first thing I listen to, to get me in the mood to drive. While I like Skynyrd better as a band, no album of theirs has ever packed this much musical kick-assery onto one CD. Peace.
