(Number 11 was F*** You by Lily Allen, btw)

It's weird; my most played songs are mostly not my favorite songs of the year, just the most catchy.

What's yours?

Well, my iPod is fairly new, hence not many plays.

1. You Belong With Me - Taylor Swift - 36
2. You've Got The Love - Florence + The Machine - 35
3. Waking Up In Vegas - Katy Perry - 32
4. Party In The USA - Miley Cyrus - 32

6. Rabbit Heart (Raise It Up) - Florence + The Machine - 26
7. Love Story - Taylor Swift - 26
8. The Climb - Miley Cyrus - 25

8. The Saturdays-Deeper (49 plays)
