background music from movies. (Examples: The Wizard of Oz, Psycho) For movies that contain both orchestral film scores and pop songs, both types of music. (Examples: Shrek series) Albums of popular songs heard in whole or part in the background of non-musical movies. (Examples: Sleepless in Seattle, When Harry Met Sally...) Video game soundtracks are often released after a game's release, usually consisting of the theme and background music from the game's levels, menus, title screens, promo material (such as entire songs of which only segments were used in the game), cut-screens and occasionally sound-effects used in the game. (Examples: Sonic Heroes, The Legend of Zelda: Ocarina of Time) Albums which contain both music and dialogue from the film, such as the 1968 Romeo and Juliet, or the first authentic soundtrack album of The Wizard of Oz. The soundtrack to the 1937 Walt Disney animated film Snow White and the Seven Dwarfs was the first commercially issued film soundtrack. It was released by RCA Victor Records on multiple 78 RPM discs in January 1938 as Songs from Walt Disney's Snow White and the Seven Dwarfs (with the Same Characters and Sound Effects as in the Film of That Title) and has since seen numerous expansions and reissues.

The album was originally issued as a set of four 10-inch 78-rpm records. Only eight selections from the film were included in this first edition of the album. In order to fit the songs onto the record sides the musical material needed editing and manipulation. This was before tape existed, so the record producer needed to copy segments from the playback discs used on set, then copy and re-copy them from one disc to another adding transitions and cross-fades until the final master was created. Needless to say, it was several generations removed from the original and the sound quality suffered for it. The playback recordings were purposely recorded very "dry" (without reverberation); otherwise it would come across as too hollow sounding in large movie theatres. This made these albums sound flat and boxy. Terminology MGM Records called these "original cast albums" in the style of Decca Broadway show cast albums mostly because the material on the discs would not lock to picture, thereby creating
