By the way, only two fo the five RBN tracks for this week showed up in the EU PS3 store. Even the Sony EU blog only lists the two.
The tracks that are available are the A Day To Remember and Rose of Jericho tracks. The other three, fail. Hopefully next week.
To add some further notes, I noticed a couple of days ago that several older legacy tracks show up as Currently Unavailable in the in-game store (incl. at least two of the Metallica tracks).
