Honestly, can anyone "get their own sound" these days? Everything has been done before. You could easily say this band sounds like this band and that band sounds like that band.
Come on now. If you're really that concerned that MIW sounds too much like Breaking Benjamin or Marilyn Manson then do one of two things.
A.) Forget about MIW and just listen to BB or MM.
B.) Start your own band and please don't dare sound like ANYTHING we haven't heard before. Influences are bad after all right?
At the end of the day, if the music is good, listen to it. If its not to your liking, don't. This isn't rocket science.
Exactly. People say their old sound was more unique when they pretty much played generic metalcore with "spooky" keyboards. And honestly, how many other bands in their scene sound like this? They're making the kind of music they wanna make and I love them for it.
