Hi All,
Long tail short, I'm putting all my CD collection back in to itunes because it refuses to recognize some albums in media player.
I have the latest version down loaded, but when i load certain albums (Brian ferry the ultimate collection)

. I tunes makes one "folder" with just two songs in it then makes another "folder" with another two songs in that 
The only difference that i can see is that the first "folder" is by Roxy music, the second "folder" is by Bryan ferry.
Ive tried to drag and drop all the tracks in to one "album folder" but it wont let me

WTF am i doing wrong ?
Any advice from itune gurus out there would be appriciated
Thanks in advance
P.S. Yes the album is a genuine purchase, not a copy.
By folder i mean an album in itunes
