Taylor released Safe and Sound for The Hunger Games soundtrack and it's one of her best tracks to date. It's very dark compared to her earlier work but it pays off and Taylor delivers one of 2012's best tracks.
#4 Jake Bugg-Two Fingers
I love this song. The vocals, the lyrics, everything is just perfection. The 2nd best song off his album
#3 Ellie Goulding-Figure 8
This song is heaven. The synth based production is Ellie's best song ever.
#2 Fun.-Some Nights
I love this song. It has such a great message and it reminds me of something Queen would release. Utter perfection
#1 Madonna-Girl Gone Wild
This is easily the best song Madonna has ever made
j/k
#1 Taylor Swift-I Knew You Were Trouble
I never though Taylor could pull of dubstep but as always the Lord surprises me and releases the best single this year that utilizes dubstep. This track is utterly flawless and is the definition of pop perfection
I actually would have rather had GGW at #1 than the actual song you posted I do really enjoy Safe & Sound though, and Some Nights as well from this set
