None More Black are also sweet. I listen to both This is Satire and LaGrecia's "On Parallels" (hear this if you haven't) every single day.
Now let's list some unpopular bands and see if we connect... :P
The Sidekicks, Rogue Set, The Artist Life, Above Them, Anchor Arms, Carpenter, The Don Ramos Players, Fear Like Us, Our Mercury, Polar Bear Club, Pteradon, Broadway Calls, Rocky Votolato (and Waxwing), Signal to Noise, Small Arms Dealer, Smoke or Fire, Latterman, Shorebirds, You Me and the Atom Bomb
I know them mostly from their split with O Pioneers!!! and sharing a spot on Quote Unquote Records with The Riot Before, who I love.
I listen to those two bands, Hot Water Music, The Loved Ones, Against Me!, The Lawrence Arms, etc. Those are the most popular bands I can list, but I have hundreds or thousands of artists on my computer that I could list as well.
For bands that sound kinda happier, like BTMI! there's And Now We're Even, Defiance Ohio, Life Rocks! and some others.
