Before I got the real thing (the promo disc), I too downloaded the crappy demo tracks...I am all for Napster, but I think it sucks that Arrival is on there.

Whether you buy/trade a CD-R of the disc from someone or download the tracks and piece a disc together - make sure you buy either the Jap or US release when it "Arrives"!

Otherwise, you'll just be hurting the band and their chance at full Sony promotion, and a major comback!
