I like most band names in the Post-Hardcore scene:
Dance Gavin Dance
I The Mighty
A Lot Like Birds
Trust The Medic
Chunk! No, Captain Chunk!
What I don't like in band names is when there are latin or complicated words. I really dislike a lot of metal band names, and it took me really long to even try to listen to Coheed and Cambria. (Although that's not Latin.)
My own band atm is called 2011 Asian Mens Volleyball Championship, which is a name you can't be neutral about, haha. We also talked about the name No Jesse, It's Poison! Which I quite liked.
