An odd question that's just been making wonder since I noticed this; is there some reason that so many anime related music CDs are coming out on exactly May 25th, this year?
[Madoka OST, A Channel OP, Astarotte OP/ED, Steins;gate ED, Nichijou ED, KamiNomi II ED, and etc]
Like some business reason that makes it a good day to release a song or something?
