         19 . The communication terminal according to  claim 18 , wherein the acquisition unit additionally acquires meta-information associated with content stored in the communication terminal. 
     
     
         20 . The communication terminal according to  claim 19 , wherein the playlist management unit records, in the playlist, the meta-information acquired by the acquisition unit, in association with identification information of a user corresponding to the other communication terminal or the communication terminal from which the meta-information was acquired by the acquisition unit. 
     
     
         21 . The communication terminal according to  claim 20 , wherein the playlist management unit additionally records, in the playlist, the meta-information in association with a playback order in which to play back the content corresponding to the meta-information. 
     
     
         22 . The communication terminal according to  claim 21 , wherein when the meta-information is acquired by the acquisition unit, the playlist management unit records the meta-information in the playlist in a manner that the playback order in which to play back content corresponding to the acquired meta-information is at the end of the playback order recorded in the playlist. 
     
     
         23 . The communication terminal according to  claim 20 , wherein the playlist management unit additionally records, in the playlist, the meta-information in association with a playback time at which the content corresponding to the meta-information was played back. 
     
     
         24 . The communication terminal according to  claim 18 , further comprising: a playlist transmitting unit that transmits the playlist to the other communication terminal. 
     
     
         25 . The communication terminal according to  claim 24 , wherein when the playlist is updated by the playlist management unit, the playlist transmitting unit transmits the updated playlist to the other communication terminal. 
     
     
         26 . The communication terminal according to  claim 21 , further comprising: a playlist control unit that, following the playback order recorded in the playlist, transmits an instruction to play back content corresponding to the meta-information recorded in the playlist to the other communication terminal storing the content. 
     
     
         27 . The communication terminal according to  claim 26 , wherein the acquisition unit additionally acquires, from the other communication terminal or the communication terminal, a playback change request for changing playback from currently playing content to content corresponding any of the meta-information among the meta-information recorded in the playlist, and when the playback change request is acquired by the acquisition unit, the playback control unit changes playback from the currently playing content to content specified by the playback change request. 
     
     
         28 . The communication terminal according to  claim 18 , further comprising: a playback information database operation unit that causes a playback information database to store a captured image captured by the communication terminal, a capture time of the captured image, and identification information of a user of the communication terminal in association with each other. 
     
     
         29 . The communication terminal according to  claim 18 , wherein the content is music. 
     
     
         30 . The communication terminal according to  claim 18 , further comprising: a content request unit that requests content corresponding to the meta-information recorded in the playlist from a content providing server that provides the content. 
     
     
         31 . A communication terminal comprising:
 a storage unit that stores one or more pieces of content;   a transmitting unit that transmits meta-information associated with content stored in the storage unit to another communication terminal;   a receiving unit that receives, from the other communication terminal, a playlist which is shared with the other communication terminal and which is for playing back content corresponding to the meta-information; and   a display unit that displays a playlist screen based on the playlist.   
     
     
         32 . A communication method comprising:
 acquiring, from another communication terminal, meta-information associated with content stored in the other communication terminal; and   managing a playlist which is shared with the other communication terminal and which is for playing back content corresponding to the meta-information acquired from the other communication terminal.   
     
     
         33 . A program for causing a computer to function as:
 an acquisition unit that acquires, from another communication terminal, meta-information associated with content stored in the other communication terminal; and   a playlist management unit that manages a playlist which is shared with the other communication terminal and which is for playing back content corresponding to the meta-information acquired from the other communication terminal.   
     
     
         34 . A communication system comprising:
 a first communication terminal and a second communication terminal, wherein the first communication terminal includes an acquisition unit that acquires, from the second communication terminal, meta-information associated with content stored in the second communication terminal, and   a playlist management unit that manages a playlist which is shared with the second communication terminal and which is for playing back content corresponding to the meta-information acquired from the second communication terminal.
