Music Supplement Help!

<p>I've been singing, and love singing. I've won a couple talent shows, played at a couple small concerts, and other stuff like that, and I sing every week at my church.
I was recently deferred from Harvard, and I decided that it would be beneficial to my application if I added a musical recording, seeing as how I emphasized slightly the importance of music in my life.
The problem is, it seems like , musical supplements , or just any kind of musical recordings sent do colleges tend to be classical in nature.
For example, vocalists tend to do classical, opera style singing.
I do not sing that genre. I'm not involved in any musical institutions nor do I receive lessons. I think skill-wise(or at least how ear-pleasing it would be), I would be okay, but I was just stuck over whether not doing something classical would actually be detrimental to my application.
So I was wondering whether singing a old school jazz song(like frank sinatra), a 70s-80s song (like Michael Jackson), and a more recent r&b style song in a total of about 10 minutes , would be appropriate to send to colleges. Well I mean i'm just trying to do whatever I can to boost my appeal, and show myself as a well-rounded person. I also put music stuff in my app, and talked to my interviewer about my musical interests. I'm not going to major in music, although I am interested in possibly minoring in it .
Do you guys think i should send the recordings?</p>

<p>Anything that shows an extraordinary skill will be helpful. The key here is “extraordinary”, which very few people are. Jazz and r&b are both helpful.</p>
