I find it frustrating that the moment I say I listen to electronic music, everyone within earshot has to say "IT ALL SOUNDS THE SAME! GARBAGE!"
This goes for anyone who ridicules any genre by telling the listener something they already noticed long ago and obviously don't mind.
It bugs me that I'm the only person I know in everyday life that can come up with an actual description of the reasons I don't like something.
Me: It sounds lifeless, almost as though they're going through the motions. Vocals that tried to sound emotional but ended up melodramatic instead, a far-from-engaging melody, and a lack of compelling reasons to listen to more of their work, or more importantly, buy it.
Other Person: Yeah? TECHNO SUCKS!
