Thanks for the information. IMO there are many factors that affect how much of a bump (if any) a URM will get. Adcoms may make considerations for Latinos who lacked academic opportunities due to income, HS, etc.
On the positive side, your first gen, low income, URM status will get the attention of adcoms. Also, the fact that you took the most rigorous courseload is a plus. And your vocal ECs seem to be strong and focused, but be aware that I'm not an expert in this field

.
Your gpa (3.7 UW) is within range for these schools. As you already know, your SAT scores are a problem. While your SES might cause adcoms to give you some slack on standardized testing, the fact that you had the advantage of a private school may negate that. And with such low scores, there is the concern that if admitted, would you be able to do the work? 500s are very low when you consider that most competitive students at the selective colleges on your list will be in the 700s. And your lower AP and Subject test scores might make adcoms wonder if your HS has grade inflation.
If you would be happy to attend UF, if it is financially feasible and if you know that you qualify for automatic admission based on your HS record or would be accepted early on during rolling admissions (I'm not familiar with UF admissions), then your list might be alright. However, if you were my child, I'd recommend a more balanced range of schools for your given stats. The very selective colleges demand applications that are thoroughly thought out and executed, and with so many supplemental essays, Why school X?, etc. to customize for each school, 12 colleges is a lot.
Are you planning on continuing in music and are you being "recruited" for your talent? I ask because, like athletics, that would make your situation different from more typical college admissions scenarios.
