People who cannot understand the difference between opinion and fact. Most of day-to-day friends are music elitists who think that if the album wasn't recorded in some guy's bedroom and released on a completely obscure indie label then it must be utter trash. No, it's worse than that. I have a friend who seems to think that if you can actually relate to or enjoy an album, it must be pop-y trash.

Also, people who cannot understand irony.
