2012 had the worst #1's, but really was one of the best periods of music.
2010-2011 is weird for me, I loved literally every song on the Year-End lists I knew of for both. Like, I don't know...music was EVERYTHING for me those years. I eventually came around to liking everything that was on the radio.
I hated 2013 so much, but it wasn't as bad in retrospect + Gaga, Drake, Katy, Britney, Eminem, and everyone else plus their mothers releasing in Q4 made it interesting.
2014 was okay, but a letdown to expectations. This half-decade has been decent.
I think 2000-2004 had the best half-decade out of all since 2000's. Probably because the Urban music @ #1 >.
