Largely thanks to watching Viga's "Idols of Anime" series, the idea of doing a "Battle of the Bands" type scenario has been stuck in my head. The problem is, I don't see an objective way to measure that sort of thing - as far as I can tell, the winner would really boil down to a popularity contest, or personal preference. It's not like we can see actual sales figures for fictional bands or anything. Is there any way to do this?
