System and method for efficient generation and management of similarity playlists on portable devices

摘要

There is provided herein a system and method that allows a user to automatically generate similarity playlists of digital media files on portable devices and, preferably, on devices having minimal computing power. The digital media files will preferably be analyzed with respect to their musical characteristics on a PC and a similarity value will be generated as a result. The similarity value will preferably be stored in a music attribute file on the personal computer. The media files and the music attribute file will be transferred to the portable music playing device. On that portable device a similarity playlist for a each digital media file will be created by comparing the similarity value of the selected song with the similarity value of the stored digital media files and selecting the digital media files that are most similar to the selected digital media file.
