Abstract: A method for automatically generating a play list based on the age of the media recording (based on released date) and the time period the media file was last played. This method uses tags on the media file to store the corresponding dates and generates a weight value on each media file by using an algorithm based on settable values for each elapsed time period of the released date and the last played date. The present invention makes the play-list more tailored to a user's listening preferences.

Abstract: The present invention relates to a method for generating a play-list of media files, includes the steps of: adjusting the current gain value in response to a control command for adjusting a current gain value during the course of a media file being played; obtaining a gain value having been adjusted; subtracting a referenced gain value by the adjusted gain value to obtain a gain difference; obtaining a weight value corresponding to the gain difference from a weight table; updating the weight value in a weight field of the media file; receiving a control command for generating a play-list; obtaining the weight value in the weight field in the weight field of each media file; and generating the play-list of the media files according to the weight values thereof.
