Whatever name you go with, just make sure it's something everyone in the band can personally relate to first and foremost. Who cares what anyone else thinks. Secondly, the name is defined by the music the band makes. With a name like Death, you'd think all they'd played was gore obsessed super fast chug single note tremolo. Or with Emperor, they don't sing about Emperors or kings or even black metal fanfare, but you know exactly who the band is because of the music they made. I could make a band called looney bananas, but it means nothing without the soul and music I put behind it.
