I Believe in Music is the second album released by singer-songwriter and actor Mac Davis. It was released in 1971, although the title song had already charted in 1970. The title track went on to become a standard and was covered by many artists in the 1970s, including a top 30 pop hit by Gallery in 1972.
Music reviewer Stephen Thomas Erlewine considered many of the songs to be more suitable for the album than on radio, and said:
The title song became Davis's signature song. His hit "Baby Don't Get Hooked On Me" was released after this album debuted, later in 1972.
