What is the name of the version of jason mraz's i'm yours that's not the acoustic version?

Question

it has more instruments than just an acoustic guitar

Answer 1

there's the demo version that's was leaked online over a year ago.

and there's the album version that's on his latest album and on the radio this summer.

does this help?

Answer 2

He originally recorded "I'm Yours" when he first wrote it 3 or 4 years ago. It wasn't necessarily released, but it was available as a download with 'Mr. A-Z'.

Then a few months ago, before 'We Sing, We Dance, We Steal Things' was released, Jason put out 3 EPs with acoustic versions of almost all of the songs. There was a different acoustic version of "I'm Yours" on there. So odds are you have one of the two earlier releases (which I think are better than the album version).
