The first music album released was "Anemoscope" which came bundled with the original release of "Kanon" in June 1999. The next release was a single, "Last regrets/Place of wind which arrives", which contained the opening and ending themes plus arranged versions of three background music tracks and a male vocal version of the opening theme. A compilation album containing tracks from the two albums was released in December 2001 called "Recollections". The game's original soundtrack was released in October 2002 containing 22 different tracks along with short versions of the two theme songs. A piano arrange album was released in December 2003 called "Re-feel" which contained five tracks from "Kanon" and five from "Air". Excluding the first two albums, each of the albums released for the visual novel version were released on Key's record label Key Sounds Label; this is due to the first two albums being released before the label was formed.
