Round robin list: Lisah, Tina, Misha, Jon, David, Erinaceous, Kate, DX, and me. Three rounds! Anyone else?
Also, I say suggest as many as you want. 'Cause I'm bossy, I like the idea of me being the ultimate arbiter of the categories, but I also like people having the voice to veto categories they dislike.
Since we are putting this up at a gmail account and not burning CDs, there is no time restraint other than how long do you really want to spend sending music files to a gmail account... Corwood's RR had 26. I think our last one was 25. I think around there somewhere is reasonable.
On the one we're doing elsewhere, we tried to limit it to 80 minutes just to have another constraint on there. However, the rule is that all categories must be met, so some songs have to do double or triple duty. I like this rule, as frustrating as it is, simply because I think constraints give people cause to be more creative. Also, I think 25-27 categories should cover all our needs. What do you think?
