Okay, one thing that annoys me is music.
People always ask me what music I like, and I always give the same response. I'm not interested in it, I hardly listen to any. They normally give me a weird look and walk off at that point.
There's two things that annoys me about music. The obsession to listen to music all the time that it is suitable. I swear, some people are now impossible to talk to because they've always got an iPod thingy in or whatever. Great that you find listening to music much more interesting than listening to me, I'll bare that in mind next time you want to talk to me.
Also, I find it really annoying people who despite having headphones find the need to play their music so damn loud the whole bus/train/whatever can hear what they're listening to, even when there's notices up not to play it that loud. I think there should be people with hammers on public transport ready to smash music playing devices up if the owner is playing music too loud.
Moving aside from the iPod thing for a moment, the other thing I find annoying is how crap the music industry is of late. I think that a few years ago, you had to be properly talented to make it to the big time. These days, there's technology like autotune that can make anyone sound good, even if they haven't got an iota of talent within them. Plus, it's more about if you've got a pretty face and a mass of female fans who seem to suffer from OCD to the point they'll tweet about you every day and write crap like "Justin Bieber gives me the strength to carry on with life." Either a pretty face or a sad story, like your parents died when you were young but always wanted you to be a singer.
I just find music all a bit pointless to be honest, but if it makes someone's life better to the point they'll waste money going to see them live, great, just don't expect me to feel the same way.
