Just throwing it out there but there ARE game genres that lazy town could fit into that don't defeat the purpose...
I know I say it to death but hey, on In the Groove (good version of DDR), I have Bing Bang, Cooking by the Book, There's Always a Way, Spooky Song and Twenty-Times Time all on my memory stick to play if I choose.
Lazy Town is pretty much about Music, Dancing and Exercise so I'm pretty sure it fits the scene, they made a DDR Mario Series shit thing after all, they could just as easily do it for Lazy Town.
