I guess the "guilty" part is because from the moment I first heard them, back in the Bon Scott days, I didn't like them. The voice bugged me, the guitars and music overall seemed very crude, very simplistic, and 100% formulated to appeal to the lowest common denominator: idiotic, hormone-ravaged teenaged boys. And I was exactly that demographic.
At the time, I was "progressing" from KISS and Aerosmith into stuff like Yes and Genesis, and liked to think of myself as musically enlightened or something. I know, I know. I'm getting better about that. But this was high school, and there was this one radio station that played AC/DC all the time. It was obviously somebody's favorite band there. But it was the radio at work, and it was the only station we could get because of some weird confluence of meteorological phenomena and where the radio sat, so I couldn't get away from it. Two AC/DC songs per hour, every hour. And every time they came on, I thought "Here we go again." Drove me fucking nuts.
But as happens so often in such situations, I eventually came around. I started to like it. And I felt strangely guilty about it. I had been manipulated. This was music specifically written to appeal to me, and I should not fall for it. But they had a couple of really good songs, and this is one of them.
