It may take me a little time, but I'm willing to put some effort into a leaderboard thread.
I've just recorded the number of blocks and calculated the exact maximum scores for OST 1.
To get the exact maximum possible score was a little tricky, but to simplify:
((Total number of blocks - 14) x 1094.8) + 5747.7 = Exact possible maximum
The first 2 notes are at 1x combo
The next 4 are at 2x combo
The next 8 are at 4x combo
The remaining notes are at 8x

I'll do this for every song, except the DLC (because I don't own it). Would be great if someone with the DLC could compile that. Once it's all done I'll try to think of a format for this, but of course I would welcome all the help I can get ?
