The difference is that I acknowledge the underground scene and am not a complete brainless moron when it comes to music.
Hipsters usually say that.
And you listen to some rather obscure shit yourself, so you're being a hypocrite.
I don't have that attitude that I THINK I'm better since I listen to music that's obscure (although most of the music I like isn't really that obscure at all). If I went by your definition, then everyone would be a hipster since we all listen to stuff others never heard of.
Although if people want to call me a hipster, then I really don't mind at all. People can call me anything they want. I had people call me an emo before, even though I'm not melodramatic, don't even like the music and I don't have enough hair to sport an emo fringe.
