The naming protocols in the latest two albums are pretty odd. Pretty. Odd.
To start with, in Friendship Games OST, they removed Daniel Ingram as the artist, while putting VA as the album artist and voice act(ress) in individual singles.
Why? I have no idea, possibly due to Sony's regulations (if you don't know, this album is co associated with a subsidiary of Sony Music Group; they are a bunch of morons).
Not to mention they got Rebecca Shiochet's name wrong (they put Rebecca Shoichet).
There's a Christmas album coming up as well (see EQD, preorder now on iTunes, release this Friday). To make things even more complicated, though they used Various Artists as album artist, we see the character names in the show appearing as singles' artists (as in Twilight Sparkle).
However, they still included Phoneix Chamber Choir and KAZUMI EVANS in the credits. I can understand the Choir because they do the harmonies; but why Kazumi? Might be an error, but wow things are getting far more confusing than before...
