Peace, love and Jason Mraz

Jason Mraz has a message for the world, and the message is L-O-V-E.

Now, we know the American singer-songwriter has always been quite the optimist, having released such sunny gems as Curbside Prophet (2004) and I'm Yours (2008).

But one wouldn't be faulted for thinking Mraz, 34, might not be feeling quite so happy-go-lucky, especially after his engagement to longtime girlfriend, musician Tristan Prettyman, was called off last year.

Of course, in true, laidback "Mr A to Z" fashion, the man has said that they are "still super friends".

In the liner notes for his fourth album, Love Is A Four Letter Word, he even thanks Prettyman for "leading me back to me", whatever that means.

Clearly, this perpetually positive dude ain't letting anything get him down - and it shows on the 12-tracker, which comes a good four years after 2008's We Sing. We Dance. We Steal Things.

Indeed, Mraz sounds high on life, and in full-on, peace-lovin' hippie mode (with scraggly hair to boot) from the get-go.

Which could understandably get a little, you know, blah, except that the guy sounds like he actually means every hopeful, sunshine-filled word.

On country-tinged Living In The Moment, for example, which kicks off with cheery whistling, no less, he sings: "With peace in my mind/I got peace in my heart/Got peace in my soul/Wherever I'm going, I'm already home."
