Cool. Did you somehow miraculously manage to find loop points, or did you do some awesome editing to make them loop, using such methods as overlapping (for smooth transitions as simply cutting and pasting sounds bad)?
And yeah, doing multiple BRSTMs then uploading is better than making one, uploading it, and then making another one, and so on... generally, I make as many from a game I can/feel like, before I get bored or want to do something, then I'll either upload those, or just wait until I've done an entire game's soundtrack and then upload a load at once.
