At least for me, I don't see them being necessarily acknowledged by mainstream community, since there is a heavy tie-in here. If a single with no tie-in at all, such as Progressive was, achieved the same thing, then I would think like that. Just like many artists out there that have big sales when their single has a good tie-in but do not have nearly the same sucess when releasing something that isn't related to anime/games/whatever at all. But in a sense, I agree that Magia is more of a mainstream song than many of their other songs.
