For those of you that solved the mystery about the song we hear throughout most of the dismal LJN game Back to the Future for NES ("The Power of Love" by Huey Lewis & the News), I want to ask you all this: were there any other licensed songs that were so sped up they became unrecognizable?

These can be songs that were heard in the movies the games were based on.

Regarding Super Mario Bros., were there any songs in the Mario universe or elsewhere in Nintendo's catalog that played so quickly or so slowly you can't tell them from the more recognizable versions?
