Firework by Katy Perry ... yes thanks to finding via MSN that a good friend was listening to it, i googled it found this clip and got hooked - such a great mood lifting song, not to mention the kids love dancing to it ;)
Heres the last mood lifting song i came across:
Something in the water by Brooke Fraser ... nothing like a good song to sing along to really.
When i'm sad or down quite often i find this slip into my head
Evanescence - My Immortal ... i quite often find watching this clip can get tears flowing.
But as a sum up ... I'd listen to anything, i'm not fussy with music just certainly have favorites - those strong lyric'd sing along ones ;)
