Why do BBMak perform 'Always Know Where You Are' instead of John Rzeznik?

On the Treasure Planet CD, the end credits song 'Always Know Where You Are' is performed by BBMak instead of John Rzeznik, even though the John Rzeznik version is used in the movie.

Does anyone know why this is?

I like the BBMak version but would prefer to have the version that is actually from the film.
