Well, sub genres are an annoying sometimes alright - although sometimes they're necessary. I think the biggest annoyance in this regard would be caused by certain music being labelled as something that it is not... or in general with new pointless sub genre names being thought up of, for the sake of it.

Personally, I've wanted for a long time to have a "Total shite" section at Spindizzy, but we haven't got around to it yet :)
