Just posted about this, I should update a bit. I think I excluded Rose Falcon (actually I may have just listed everybody, but I don't think she makes the cut). Of your ineligibles, I would argue for reinstating Lillix. (1) They sound like the Killers now (major label indie) and (2) they've been at least as big a flop as Brie. I reluctantly accept that Skye probably doesn't count in 2006 (she'd be a shoe-in for the 2004 awards, or even 2005 with a year lag, when production could have qualified her despite being distributed on a major). If one-year lag counts, which I think is reasonable on a case by case basis, I would tentatively include Hope Partlow on the Brie Flop Clause, but tough call.

Of the probably not good enoughs, I only really like Go Betty Go. They're on Side One Dummy, same label that put out Gogol Bordello's last record, and their new album comes out tomorrow. But they have a new lead singer now and everything I know by them is older material, 04/05 (might want to check em out here).
