I feel disconnected from everyone else my age?

Hi, I'm a 20 year old male and I've always felt different to people I meet in college and such. Example: When someone says "Aaaw mate! we went out Saturday and got WASTED! We went and did this and Tim puked! then Katie passed out on Sam!" and so on and so forth I think to myself "Yes drinking myself to the point where I can no longer control my bodily functions and can no longer recognize the pavement from my own bed sounds brilliant....."I don't feel like I can talk about anything with normal people in my age group I hate modern music I listen to rock from the 70's and early 80's and what most people consider "fun" I find downright stupid and pointless, To be honest when I look at most of them I am reminded of a bunch of chimps jumping up and down shrieking and flapping their arms because mummy and daddy can't tell them what to do any more. Am I just a cynical heartless ****?
