I'm sick of reading/hearing that. Jesus, music is not a joke and being proficient at an instrument is a hell of a lot more rewarding than giggling and hitting out of tune notes. I don't understand why it's such a big deal if women are in bands. I think it's because unfortunately most conform to the stereotype of being barbies with guitars or talk about how they can't really play.
What's the point in that? Seek inspiration in girls like the ones below and let's show the world that we ARE talented. Learn your trade.
