I've been thinking, since the show started being recorded in high definition, which characters have had their own songs? I'm sure that Elmo has had many songs since, though I figure most are either with a celebrity or other characters. As for who I know has had a song of their own since, I know there's been songs from The Count (I recently found an HD clip of him singing about the number 8, not sure what the title is), Ernie (I Wonder), and Abby Cadabby (Hurray for Broccolli, and she's also sang Guess the Season Song with Zoe and Rosita). Anyone else? Oh yeah, and Elmo and Cookie Monster have had some songs in animated form. Would those count?
