While I commend you for dreaming big, my best recommendation to you would be to set your sights on some attainable goals and have a little focus. There are many, many colleges that have good music programs. Where do you want to be in 3-5 years? What is your definition of success (fame does not always equal success). And if you have a true and genuine interest in studying music, I would not let the focus be on "becoming famous". A better question, however, may be "I love to sing and to play music but I am afraid it may be a very competitive space and I may not be able to sustain a living. What types of things can I do to help fuel this passion but also make it into a sustainable career path?"
I would encourage you to understand where your musical talent lies. How well do you sing? Do you need to invest in singing lessons? Do you play something? Can you start, perhaps, with a YouTube video series to have your music exposed in the digital world? Plenty of people are found that way. If you are planning to have a career, I would also have a backup plan. What should I study or what would I be doing if this doesn't work out for me?
I would start by looking into your local colleges to see what types of music programs they offer.
The fastest way to get famous that I know of, if you are truly that talented, would probably be to go audition for X Factor.
Good luck to you,
You need to start doing actual gigs if you're not already. Sing anywhere you can. The rest will follow. Good luck! Oh by the way, "Luck" is preparedness meet opportunity.
I can't recommend any schools -- there are too many and your question is pretty broad. I will say this about your desire 'to be famous": When you're in the race, don't be so focused on winning that you forget to run.
