Setup watch outside the home of a successful person with lots of money. Stalk them thoroughly. Be sure to make many mental notes of the specific details of their life.
Follow them when they leave their home until the most opportune moment to throw them in your trunk.
Brainwash them into thinking your music is something new and you are the next big thing.
Immediately escort them to their bank and get cash.
Take that money and move to the Islands because there is a 99% chance that your going to lose all their money.
Start a beach dance club on your island and when it's profitable send the person from whom you stole the money all of it back with interest and a nice "thank you for letting me kidnap you and steal your money" note.
Now that you are rich look at your own money…. Do you really wanna spend it all on your music career? If so go for it and good luck!
Now, this is just my deranged since of humor with a bit of reality...
