Sometimes, it's easy to get so excited that you spontaneously burst into song. After all, that's the logic behind most musicals, no? Microsoft's OneNote team took that idea and ran with it, cribbing from Les Miserables in the process. See, after setting its note-taking app free last month, the team had reason to celebrate. Naturally, it picked an upbeat song ("One Day More") from one of the saddest musicals of all time to do so. Video evidence of the team's "Weird Al" skills is after the break, but try not getting the track stuck in your head -- it's for the good of everyone, really.
