Ocean's 11/12/13 soundtracks - Actor voices?

[OscarBluth]

I'm previewing these soundtracks on Amazon and some tracks have dialogue from the actors on top of the music. Is this just the preview? I don't know why the preview would be different, but it seems weird to have Clooney's interview with the parole board on the soundtrack instead of just the music.

A lot of soundtracks have dialogue and sound effects from the movie spliced in. These soundtracks are probably no different. In my oppinion it can really ruin the music. However it is cool sometimes when they include dialogue but as seperate tracks and not intruding on the music.
