Somewhere into the so-so "Itsy Bitsy Spider" segment, the sinking feeling that Kids' Favorite Songs 2 is strictly sequel material sets in. This is a march down Sesame Street on a slow day, when the loopy monster misunderstandings and goofball gags miss a rare beat or two. Still, making merry is what the Sesame crew does best, and they succeed here, if on a less brilliant level than we've come to expect. All the usual favorites, like "If You're Happy and You Know It" and "The Ants Go Marching," get the gang and their real-life kid friends grooving, and a running joke involving a renegade meatball keeps kids 18 months to 5 tuned in to the end. Elmo hosts.
