There are a number of unused tracks listed, but not accessible, within the code for Super Smash Bros Brawl. This series of videos is meant to illustrate what these tracks may have been like if they were usable in the game. All tracks are taken from the album compiled and edited by EditorArtist. You can download the full album of unused tracks from:

~~Note that these are at best guesses as to what the songs would've actually sounded like if they were in the game. Since it is not possible to hear them, the song selections are only educated guesses based on the filenames.~~
