"Crazy on You" is a song by American rock band Heart from their debut studio album, Dreamboat Annie (1975). It was released in March 1976 as the album's third single in Canada[1] and the album's debut single in the United States. It reached the top 25 in Canada and the top 35 in the US. It found more success in the Netherlands and Belgium where it peaked at number 2 and 13, respectively, in early 1977 after its release as the second single from Dreamboat Annie in those countries. It is considered one of Heart's signature songs as it is one of the most played tracks on classic rock radio stations in the US.[2]
