"I'm Yours" - Jason Mraz.
A hit all over Europe this year but....oh you know the rest. Still there is hope: I heard it on my local radio station today at work, and I leapt out of my seat and yelled "Jason Mraz!!!!" (Needless to say I got some funny looks and no-one seemed to share my enthusiasm for the song, but hey I still love it anyway).
This song got me into his music and I am now a fan of his laid-back gentle lyrical acoustic sound, which musically comforted me through a turbulent summer.
