I'd hate to say this, but I'd say I like this guy's flow better than Kevin's in the original. It would have been so easy to just pop out one of those jumbled, poor translations of songs that you see once every so often, but this one manages to keep the rhythm. Maybe even sounding better. Of course, my Spanish is rusty. Was this the 26 letter Spanish Alphabet or did it include the variant letters?
Also, I've always been a little confused by this one. I agree, it seems that the Sesame Street music writers have no clue what Rap is. This almost sounds like Disco with rap style lyrics over it.
