Who sees and/or reviews art supplements?

<p>I'm applying to some commercial music schools (USC, Belmont, etc.) and I was wondering who sees my supplement. It's just some videos of me responding to questions and some recordings of my music. So would my main admissions officer see them or are there school of music admissions officers/teachers who decide acceptance for the school of music? Also, if my main admissions officer sees them, would it be taken into account or not?
Thanks!
