I kinda like the date sort. I encourage them to sing something they haven't sung in a while.
In this same vein as the original poster, I made a big oops the other night. I was trying to trim down the singers database. I listed all the singers and then sorted by # of entries. I highlighted all the ones that had 0 (zero) songs and hit delete. What in fact happened is I deleted A-R. Not what I had highlighted.
Luckily, I had a backup for just such an emergency
