Look towards your genre for inspiration
Your band name should reflect the genre of your music. Words alluding to destruction―'death', 'smashers', 'slayers', won't seem right for a peppy pop band. Anything remotely happy, like 'unicorns', 'rainbows', or 'summer' can't be part of a band name that's into emo. Unless you want to go dramatic with a cool ironic name―as that would work really well.
