Sadly, this thread is from 2009. When this started, these young hipsters were keeping their myspace cool and waiting for those torrents to download. Unfortunately, no one can add to this list of cool music as cool young high school graduates under 25 don't exist anymore. Even the OP is now in his 30's, probably married, owns a raft, and may even fall into the group of completely uncool dads and beer gutted hairy rafters.
So this brings a philosophical question. If this thread was intended to exclude all old uncool opinions from idiots over the age of 25, then are all of the fresh hip opinions expressed back in 2009 now stale and uncool, or is their coolness preserved forever like canned spam?
