Combining disparate tracks to create new songs, a.k.a. mash-ups, is big in the U.K., but this chaotic mess isn't likely to find an enthusiastic audience on either side of the pond. For the remix to Houston's gripe track, producer C. Haynes laid a random Nelly verse and some whistle beats on top of Houston's vocals. It's as if someone opened the door between two rooms and cranked warring stereos. We humbly suggest closing the door. And locking it.
