Leona Lewis - Better In Time
Beyoncé - Best Thing I Never Had

Any upbeat/catchy song. The sad ones always make me sadder.

Beyonce - Me,Myself and I

Breakaway by Kelly Clarkson, Part of Me by Katy Perry, and Follow Your Arrow by Kacey Musgraves are my go to's.

i listen to music that matches my emotions, so i listen to chandelier and all too well when i'm sad (depending on what i'm sad about), and hermit the frog (marina) and never again when i'm angry

clean has really been a "moving on" anthem for me though and that's helped a lot

part of me - katy perry
i don't care - cheryl cole
shake it off - taylor swift
