A Capella, Anyone?

[Ni-Juu]

Personally I'm addicted to college A Capella. I've seen upwards of 30 different groups perform and I have sooooo many CD's it'll make you dizzy. Right now I'm listening to the UNC Achordants, but that'll only be for probably the next 10 minutes and then I'll change to some other group n_n
So...anyone else share my passion for this music?
