A method and system for providing easier listener access to information about musical works and other audio programming broadcast by a digital radio station includes broadcasting contextual information about the audio programming along with the audio programming. A receiver separates the audio and data signals giving the listener access to the broadcast content and the associated information about that content. The system may also store the contextual information about the programming for later reference, for example ordering a recording of the programming.
