"Crazy on You" is a song by American rock band Heart from their debut studio album, Dreamboat Annie (1975). It was released as the album's third single in March 1976 and peaked at number 35 on the US Billboard Hot 100 on April 20. Despite moderate success on the pop charts, the track received heavy airplay on FM Album Oriented Rock stations, which drove sales of the parent album, and the song actually charted again in early 1977. It remains one of Heart's signature tunes and is still a staple on US classic rock radio stations.
According to lead singer Ann Wilson, the song's lyrics tell of a person's desire to forget all the problems of the world during one night of passion. She said she and her sister wrote it in response to the stress caused by the Vietnam War and social unrest in the United States in the early 1970s.
Co-writer and guitarist Nancy Wilson, who played the acoustic guitar intro called "Silver Wheels", said the rapid rhythm was inspired by The Moody Blues's 1970 song "Question". The guitar riff was created by Roger Fisher during recording sessions. The song turns into a fast-paced rock song that was the band's signature sound in their early years.
