Not many people realize that the real creative genius of Jason Mraz in (what is probably) his best song ever (composed, written and performed by Jason Mraz himself), "I'm Yours", is his masterful implementation of the advanced self-harmonizing and self-synchronizing technique (technically known as a round or perpetual canon) pulled off perfectly in having 2 Jasons singing simultaneously (digitally enabled of course, but the beauty of it is that Jason could self-conceive of this silently in his head).
