I tend to become obsessed with songs about 3 years after they're popular. To whit, my current playlist includes:
"Forever" - Drake
"Black Sheep" - Metric
"We're In This Together" - Nine Inch Nails
Actual current music that I enjoyed this year?
Adele, 21, particularly "Turning Tables" and "Set Fire to the Rain."
Mumford & Sons, Sigh No More, which totally counts as a 2011 album because that's the year it won awards, and it's still getting nominated even though it came out in 2009. I love singing along to their songs, all the more so because Mike can't stand them.
Florence + The Machine, Ceremonials. Go ahead and don't sing along to "Shake It Out."
Foo Fighters, Wasting Light, still making awesome rock music.
The best (and only) concerts I attended this year: Linkin Park and Rush! Yeah, I'm hella current.
