Grandpa's Favorites 2012 (GC3MQV9) has been archived due to the demise of Xtranormal.com (and because the songs we used are now "ancient"), and we have created this new puzzle to replace it. Like Grandpa's Favorites and Grandpa's Favorites 2012, this puzzle is a merger between our kid's interest in 97.5 NOW FM and the latest the Internet has to offer. We hope that you enjoy solving it as much as we enjoyed making it!
Congrats to LTF1999 on being First to Find!
