In addition, the user can select a playback method for the selected sound source. The playback method of the sound source includes sequential playback for playing back in the order registered in the play list, random playback for playing back randomly, and repeated playback for repeatedly playing back the selected sound source.

The mobile communication terminal 110 determines whether a sound source to be reproduced exists in the mobile communication terminal 110 (S240).

When it is determined in step S240 that the sound source to be reproduced exists in the mobile communication terminal 110, the mobile communication terminal 110 reproduces the corresponding sound source stored in its memory unit (S250).

However, when it is determined in step S240 that the sound source to be reproduced does not exist in the mobile communication terminal 110, the mobile communication terminal 110 requests the sound source streaming service from the sound source server 150 (S260). The sound source server 150, which has received the sound source streaming service, loads the sound source from the sound source database 152, converts the sound source into streaming data, and transmits the sound data to the mobile communication terminal 110.

The mobile communication terminal 110 receiving the streaming data plays the corresponding sound source (S270).

After the reproduction of the sound source is terminated, the mobile communication terminal 110 determines whether the current sound source is the last reproduced sound source selected by the user (S280).

If it is determined in step S280 that the current sound source is not the last playback sound source selected by the user, the mobile communication terminal 110 selects a sound source to be played next (290). The process returns to step S240 to repeat the playback process.

However, if the current sound source is the last playback sound source selected by the user in step S280, the mobile communication terminal 110 terminates playback of the sound source.
