GUSTCD-10001: SAKIYA=RUMEI Ar tonelico III hymmnos concert side. Blue

[LiquidAcid]

I was wondering how this "Deluxe Edition" pack should be handled:
http://www.amazon.co.jp/dp/B002YXSR9C/?tag=vgmdb-22

Looks like it contains both the red and blue album. Currently it's linked from both the red and blue album in the "available at" section.

I'm also wondering why e.g. CDJapan is listing the red album, but not the blue one. Might have something to do with the publisher (red is TEAM Entertainment, blue is Frontier Works), which raises the question why the Hymmnos album always have to come from two different publishers...
