As much as I love going to see live music, there are a few things about the whole process that kind of bug me. For instance, the transition between sitting and standing is way awkward. Unless you're the absolute first one to stand up (kudos to that person), you inevitably find yourself thinking "Oh...okay, so this is a stand up song. I guess...well, the people to my left are standing...and that couple in front of me are, but the people behind me are still sitting. If I stand I'll block their view...but if I stay seated people will think I'm not enjoying myself or I'm an uptight prick. Okay, now more people are standing, dang it! I should have stood earlier, now if I stand it'll just look like I'm standing because everyone else is standing, not because I'm feelin' the music and want to express myself through awkward white person hip gyrations and hand clapping."
And then by the time you finally decide to stand the song is over and everyone is seated.

Another thing that really grinds my gears is how loud the music is. I love rock. I love it loud. I was in a band once, we played loud. But there are different levels of loud. In a library if you fart and someone 10 feet away can hear it, that's loud. I don't mind that kind of loud. I mind the kind of loud that occurs when 6 days after the concert your ears are still bleeding you're not sure if the ringing in your ears is from the telephone or your eardrums slowly dying.
