Music in Super Smash Flash 2

The music in Super Smash Flash 2 has been expanded to include not only tracks from the Super Smash Bros. games or any other derivative game but also new custom tracks composed and arranged exclusively for the game by the SSF2 Audio Department. Additionally, there can be multiple music tracks, the alternate music tracks, for the same stage.

Super Smash Bros. series
The following tracks, with the exception of Intro/Main Theme (Brawl), are completely custom made, which means they are new themes never heard before in any of the Super Smash Bros. games. They are retroactively listed under the Super Smash Bros. category as developers consider any piece of content that does not fall under the banner of any existing franchise is classified under a sort of "misc. franchise", which turns out to be the Super Smash Bros. series banner.
