Okay so it's been done before. But I think these are really good:

Yo La Tengo - means "I have it" in Spanish apparently, some baseball term. Just sounds really cool.

Taking Back Sunday - from what? but it's a great name.

Neutral Milk Hotel, cos sometimes random words can work

Converge and Cursive are both cool names

At The Drive-In is an EXCELLENT name.

Hope Of The States - great name, average band.
