OP: If you are interested in both journalism and music, then you should definitely take a good look at Northwestern and USC. The Stanford name sounds really great, but the acceptance rate for unhooked students is probably less than 2%. NU and USC will by no means be easy, either, but you might have a decent chance if you apply to one of them early.
Your grades and ECs look fine. Therefore, I would only suggest that you retake the SAT in October. If you can bump it to the 1500 level, I think you will have a decent shot at both schools.
Good luck!
