Andy Grammer and VEVO had an interactive Choose Your Own Adventure type of music video for his song "Keep Your Head Up", letting viewers pick the scenarios in the music video as it happened. The most-popular scenes were put in the final cut of the music video, which also has a cameo by Rainn Wilson.
For those of you who played along, you can see if the scenes you chose made the cut (I only had 2. LOL oops). And if you didn't participate earlier, you can still do so here: Interactive Video
