Tried again, pianosheets is still not letting me create an account.
I'm not a fan of buggy sites much. Especially when they tell me I have to shut off my cookie-blocker.
The anti-leech notice at the front could be the problem. If you don't have a 1:1 upload to download ratio, they tack a delay onto your downloads... I think up to 40 hours for 0.3 ratio.
As for music, CT midis are all over the place. But other than that, I don't see what else one could have. All Chronicles has is information about each soundtrack and links to the OCremixes (all of which I own already anyway)
