Well, this ties into my question about the /B on Avex Trax albums. The conclusion was that the /B just means it's a 2 disc album (in most cases, it seems the second disc is a DVD), and it's probably the preferred way of writing the cat number.
So yeah, these are duplicates so I'll combine the info and strip down the other so that you can fill it with a new album.
EDIT - But these are Hats Unlimited albums. Is that label somehow related to Avex? Btw, the scan clearly shows the /B on the sticker in both cases, so I'm sure it's the preferred cat.
EDT 2 - Ok, everything relevant has been moved over, and the
dupe is ready for a new album. Thanks to Squall for finding this.
