Last year, I stayed 2 tents down from these dorks who jammed their iPod all day, which wouldn't have been too bad if every band wasn't Audioslave, Sublime, Nirvana, and every other alt rock radio band KROQ has shoved down my throat for decades. 2-3 hours of this got so god damn annoying and by Sunday I wanted to slap the shit out of everyone in their party.
So how do I prevent this in 2011? I don't want to be a dick but I will not be woken up at 8 AM to the sound of Chris Cornell removing Rage Against the Machine's balls.
I also hate people that make mix CD's of Coachella artists and play them all weekend. I heard "Stylo" and "Woo Boost" approximately 950 times between Thursday night and Monday morning. THE REAL ARTISTS ARE PLAYING FOR A REASON.
