25,00 Yen comes out to be... $30?
Damn, that's alot of cash to ask for just a music album.
I don't really like IA though, so whatever. Half those songs I could swear are being sung by Miku, on certain octaves they sound very alike. But aside from that, all those IA songs lack the hard beats that tend to draw my attention, and general catchiness.
That reminds me, it's been awhile since a song has really stood out to me. The last thing that I really enjoyed was.... the No Thank You remix, I think? I might be getting a bit oversaturated on Vocaloid music.
