If I add the Albums I have in My Music folder, iTunes seems to split them in half!..by which I mean for example take Iggy Pop's Brick by Brick, there's 2 album icons for this tracks 1~9 and another that tracks 10~14 instead of one single album, It does this with several others also, which makes it look like there's more albums than I have
