For a little bit of help - don't send it or call it a "sponsor me" tape, call it a promo or promotional video, it sounds more professional and wont get instantly thrown in the trash.
As far as music, it depends on the style of edit and who you're sending it too. Don't pick the most thug song on your playlist - again this professionalism. Think of this as a job interview, you wouldn't show up in jeans a tall tee and you icons on would you? (I hope not - cause unless you're looking to work at McDonalds forever this is a bad way to get a job). Pick something original, classy, and exciting (So NOT Biggie - just cause it worked for Wallisch doesn't mean it will work for you). And remember, you're selling yourself, so make it something that explains you (the entire edit - not just the music).
Sorry I don't have any beats to pick from, but hopefully that'll help you pick one and get you a sick sponsor.
