Sadly I can't really say I remember a lot of Muppet Babies songs just off the top of my head, but here's a list of what I can think of and enjoy so far...
"I'm gonna always love you"- Although not from the show, still a great song.
"We Love Cartoons"-It's an enjoyable tune.
"You're Special"-From the episode "My Muppet Valentaine", that's song is so touching, it brought a tear to my eye the frist time I heard it and I find myself still tearing when I hear.
Wow there goes some man points for me,
. Just playing. But all Muppet Babies songs are great.
