they are definitely a b-side group, tons of bsides have gone viral or outclass the title tracks imo

from crazy: 1800-hot-n-fun (poprock)

but i recommend just going through their entire discography, most of it is 4-5 song mini albums so you go through it pretty quick and there are lots of "hidden" gems
