Actually felt like doing the official NBs next, so I'll work on the Fifties after I've done officials 21-40. This one is more of a showcase than an actual band, since I'm pretty lazy to make a proper band of these guys. Also 12 had to be placed close to the center since her band move can get quite clustersome. Feel free to use these guys, along with the Thirties and Forties. Credit may be necessary.

And whoever originally made 18's sound. Most of these were edited through Beepbox, Online Sequencer, and Audacity.
