Why are we such music snobs?

Sometimes it’s generational- someone will say, “Oh they couldn’t POSSIBLY be effected by The Beatles (or Nirvana or Benny Goodman etc) if they weren’t even born when the music was made!”

Sometimes it’s genre- “Country music, isn’t music!” or “You can’t have a real appreciation for real music unless you know your classical.”

Sometimes it’s pride for the obscurity, “Well, I used to like that band until everyone else started to.” Or “OMG I can’t believe James Hetfield cut his hair- what is he trying to be a Backstreet Boy?”

Why do we act this way? Personally I’m guilty of this. I’m only 28 and I’m already like, “The Jonas Brothers!!! That’s not real music! When I was your age I was in my room, inches away from angsty thoughts of suicide with Everybody Hurts playing because my Dad caught me ripping holes in the elbows of his flannel shirts and trying to sneak them out of the house in my backpack! ”
