       15 . The content player apparatus of  claim 13 , wherein:
 the weighting information corresponds to relative densities associated with the content items, and   the controller is configured to generate the playlist based on the relative densities, such that a content item associated with a low relative density is listed at a higher position in the playlist than a content item associated with a high relative density.   
   
   
       16 . The content player apparatus of  claim 15 , wherein the controller is configured to reorder the playlist by:
 modifying the relative densities associated with the content items listed in the playlist in response to the detected acceleration; and   reordering the playlist based on the modified relative densities.   
   
   
       17 . The content player apparatus of  claim 12 , wherein the controller is further configured to restore the order of the playlist to the first order after a predetermined period of time elapses from detecting the acceleration. 
   
   
       18 . The content player apparatus of  claim 12 , further comprising:
 an output device configured to output, to a speaker, a signal based on the playing of the content items; and   a display device configured to display the playlist.   
   
   
       19 . A method performed by a content player apparatus, comprising:
 receiving a playlist listing content items in a first order;   detecting an acceleration of the content player apparatus; and   reordering the playlist into a second order in response to the detected acceleration.   
   
   
       20 . The method of  claim 19 , further comprising:
 storing weighting information associated with the content items, the weighting information indicating a playback priority of the content items; and   generating the playlist based on the weighting information.   
   
   
       21 . The method for  claim 20 , wherein reordering the playlist comprises:
 modifying the weighting information associated with the content items listed in the playlist in response to the detected acceleration; and   reordering the playlist based on the modified weighting information.   
   
   
       22 . The method of  claim 20 , wherein:
 the weighting information corresponds to relative densities of the associated with the content items, and   the playlist is generated based on the relative densities, such that a content item having a low relative density is listed at a higher position in the playlist than a content item having a high relative density.   
   
   
       23 . The method of  claim 22 , wherein reordering the playlist comprises:
 modifying the relative densities associated with the content items listed in the playlist in response to the detected acceleration; and   reordering the playlist based on the modified relative densities.   
   
   
       24 . The method of  claim 19 , further comprising restoring the playlist to the first order after a predetermined period of time elapses from detecting the acceleration. 
   
   
       25 . The method of  claim 19 , further comprising:
 playing the stored content items in the order indicated by the playlist;   outputting, to a speaker, a signal based on the playing of the content items; and   displaying the playlist on a display device.   
   
   
       26 . A computer-readable storage medium storing program instructions which, when executed by a content player apparatus, cause the content player apparatus to perform a method, the method comprising:
 receiving a playlist listing content items in a first order;   detecting an acceleration of the content player apparatus;   reordering the playlist into a second order in response to the detected acceleration; and   playing the content items in the order indicated by the playlist.   
   
   
       27 . The computer-readable storage medium of  claim 26 , the method further comprising:
 storing weighting information associated with the content items, the weighting information indicating a playback priority of the content items; and   generating the playlist based on the weighting information.   
   
   
       28 . The computer-readable storage medium of  claim 27 , wherein reordering the playlist comprises:
