Van Halen (1978). I'll never forget my reaction when I first heard this song on the radio, in 1978. I was in disbelief. I had been a head-banger for four or five years and had been to many concerts. I loved bands such as Led Zeppelin, Black Sabbath, Kiss, Queen, and Aerosmith. This song (and the album of which it was a part) blew my mind. It was unmistakably hard rock, but the harmonies were exquisite. The music was clean and pure, with awesome guitar riffs, explosive drumming, and thudding bass. Listening to the song now takes me back to 1978, when I was 21 years old. I'm glad I got to see Van Halen in concert, late though it was.
