Taken from their debut album Dreamboat Annie, "Crazy On You" is Heart's highest-placing song. Lyrically, it deals with the desire to forget the problems of the world with one night of passion, and Ann Wilson revealed during an interview on Private Sessions that the sisters took inspiration from the Vietnam War and social unrest present in the early 1970s. Despite only peaking at #35, it is considered one of Heart's signature songs.
I'm very, very, very glad it placed higher than "Barracuda" and "Alone". That is all.
