Music navigator for digital audio playback

摘要

Methods and apparatus are provided for organizing pre-recorded digital compressed audio files for convenient playback on a device installed in a moving vehicle. The apparatus comprises a scanning function that orders the files into categories, such as "Artist" and "Album", which are each linked to an index of their associated tracks. The indexing scheme provides a user, such as the driver of an automobile, an intuitive method of finding a desired track with minimal distraction.
