I've been rediscovering Rap a bit this week: Kanye West, Outkast, N.W.A., Wu Tang Clan.
Apart from that, I've listened to:
Fiona Apple - The Idler Wheel Is...: Probably my favorite record of this year, just amazing!
My Bloody Valentine - Loveless: A classic, and not without reason.
U2 - Achtung Baby: Any U2-hater should listen to this, The Joshua Tree and The Unforgettable Fire, then try telling me again this band is crap. While I agree that U2 isn't what it used to be, these records show what an amazingly great band this was.
Japandroids - Celebration Rock: Celebration Rock indeed.
Jack White - Blunderbuss: One of my favorites of 2012.
Joy Division - Unknown Pleasures: If you're wondering why this band is so legendary, just listen to this.
Alex Turner - Submarine OST: First solo effort by the Arctic Monkeys' lead singer, and quite a succesful effort.
