The majority of songs performed for all of the albums were by Alexz Johnson. The first two albums contain only songs sung by Johnson, but starting from Songs from Instant Star 3, only four songs per album featured her vocals. It was originally planned for all the albums to be entirely performed by Johnson, but legal issues prevented her from doing this for the 3 and 4 soundtracks.

Songs from Instant Star Two is the soundtrack album for the second season of the Canadian television show Instant Star, entirely performed by Alexz Johnson. The album was released by the Orange Record Label, produced by Matt Hyde and Dave Ogilvie and executive produced by Stephen Stohn, who also is an executive producer of the television show. Background vocals are performed by Katie B on most of the tracks and Leslie Stanwyck on track 5. In the show, Jude's album was titled "Learning Curve".

Released in 2006, The N Soundtrack contains songs from Instant Star, and other shows airing on The N and CTV.

Songs from Instant Star Three is the soundtrack for the third season of Instant Star. In-show, Alexz Johnson appears on 10 tracks, but her contract with Capitol Records produced legal issues that prevented Johnson of being featured in more than four songs in the album. She was replaced by other artists, including other performers, writers and producers. Tyler Kyte's character, Vincent Spiederman, records a solo single (thus far in the series), and Cory Lee's character, Karma, also has a musical career in which she will be recording with limited relevance to the show/soundtrack.
