I had such a permit for the T in Boston. No audition, but the application asked us to list recordings or other experience. They asked me again when I showed up in the office to get my picture taken. There are some fantastic musicians who are busking, especially string instruments - classical guitar, violin, and for many years there was an elderly Chinese guy playing the erhu at the Park Street station or above ground at Harvard Square.
