song from in a store...

Hey everyone... does anyone happen to know of this song that has a girl singing and its kind of alternative and some of the lyrics are " and nothings gonna change my mood/mind" ???Thanks!!

Is it:

Nothing's gonna change my mood by Christian Walz

ake a breathe again..
see them walking hand in hand
what is more depressing than seeing
someone knowing nothing more than she's so beautiful and
has no problems of her own
Never thought that i would care
see him messing up your hair
I said I'd keep my normal cool and
never lose my peace of mind
over stupid things she does and says
but less mess I confess in my sore head
if I just would leave, but..

Chorus:
Nothing's gonna change my mood
Nothing's gonna change my..
Nothing's gonna change my mood
Nothing's gonna change my..
