Additional "Extended" Classification

[Fivda]

Mostly refers to tracks from rhythm games that have been extended for the sake fo the album.
Neither the "soundtrack", "arrangement" or "remix" classifications really represent those well enough- they're not the game cuts, but they're not really arranged into something else or new altogether, as the intent is just to go beyond the general 2~3 minutes mark that is often imposed on rhythm games. This would greatly help make the product pages for such games much more comprehensive as well.
