Yeah something's bothered me for a while now. I know like maybe two people actually /buy/ anime OSTs, but it's always weirded me out that for every single anime that exists, there seems to be not only 1 but like 2 or 3 soundtrack albums + PIANO KARAOKE version of it. Are these things like, would you actually find them in a store in Japan or are they a mail-order sort of thing? Are they limited release, like it's easy to find on the internet but only a thousand or so physical copies were made? Because the only equivalent I can think of here is like, it seems like every shitty movie has a soundtrack album but it'd be hard to just pick it up in a store. Even thinking of an anime as a TV series, does stuff like HEROES even have an OST yet?
Edit: Even for the obvious, if you consider it a cartoon was there any CATDOG OST or anything over here?
