Help in selecting music supplement!

I have talked with admission officials from Yale and Brown. Both of them said that it’s okay to submit a cover of any modern pop genre song(s) as a music supplement. I have trouble singing in falsetto, but other than that, my singing is good. Could you guys please suggest any song or songs??

You can post this in the music forum, I would caution you that music supplements will only help you if your talent and accomplishments justify it. The supplement can have a, a music resume, and letter(s) from teacher(s). If you are going to submit, you should probably have some ideas of what you want to sing. Maybe someone on the music forum can suggest something though.
