Dunno... maybe gaming character or campaign-related themes could be fun? That way, even if I knew/already had a given song, I'd be interested to see which songs you picked, if that makes sense. Or we could try some fairly broad themes, like 'war' or 'love' or something that would make it less likely we'd be able to guess right away what songs would be picked.

And yes, you are a dork. *loves*
