Harmonix is giving the gift of VidRhythm [$1.99] away this holiday season. Soon, the crazy, but always hilarious audio and video mash-up app will go free indefinitely. Also, it’ll receive one of its biggest updates at the same time — twelve new tracks, including “Jingle Bells" and “Deck the Halls, six new video styles, an all new pitch correction mechanic, and an iPad 2 and iPhone 4/4S-exclusive YouTube export upgrade to 720p are all a part of the new package.

We spent some time speaking with the man who spearheaded VidRhythm at Harmonix, Josh Randall, in this week’s bonus edition podcast. Randall and I go deep on this update and many other things Harmonix, so check it out if you want to hear this news and other bits from one of the creators. And, hey, I also think you’ll leave the conversation with a pretty good idea of how much music truly matters to the studio and how iThing stuff figures into its future. Later today!
