Train, what I mean by 'freebie' is that no one will get eliminated right away. It's for the benefit of people like you and lonestar (who hasn't played since my first roulette, and got eliminated in the very first 'culling' round of that one), and home who hasn't played since the first roulette.
Bands submitted in this round won't be banned after this one. I'll only start banning artists after this round is done. Essentially, nothing you do this round will have an impact later - it's just to save your ass because some people here know very well what I like and others don't really have a clue. Test the waters.
Basically, king nailed it. I have a wide musical taste.
