The audio system (20) includes a switch (42, 142) selectively operable in at least two modes, the switch operable in a first mode for tuning the radio tuner (23), and operable in a second mode for fast track searching and selecting for playback one of the audio data files. The audio system (20) also includes software enabling a processor (26) to read the filenames of the audio data files stored on a compact disc, sort the filenames into an alphabetical index (172), and display and access the audio data files in the order of the alphabetical index.
