a music acquisition portion to acquire the music data from the music storage portion based on the information contained in the metadata; and

a control portion to control the music playback portion to play back the music data distributed from the distribution server and the music data acquired from the music storage portion by the music acquisition portion.

2. The information processing apparatus according to claim 1, wherein

the control portion controls the music playback portion to sequentially play back the music data distributed from the distribution server and the music data acquired from the music storage portion as music having the same or similar feature.

3. The information processing apparatus according to claim 1, further comprising:

a music analysis portion to analyze music data to be played back in the music playback portion and obtain information about the music data.

4. The information processing apparatus according to claim 3, wherein

the music analysis portion obtains information about a tune of music data, and the metadata acquisition portion acquires metadata containing the information about the tune.

5. The information processing apparatus according to claim 1, wherein

a playback ratio between the music data prestored in the information processing apparatus and the music data received by the music reception portion is variable in the music playback portion.

6. An information processing apparatus for playing back content data, connected to another information processing apparatus over a network, comprising:

a content storage portion to store content data;

a content playback portion to play back content data;

a metadata acquisition portion to acquire metadata describing information about the content data being played back in the content playback portion;

a metadata transmission portion to transmit the metadata acquired in the metadata acquisition portion to the other information processing apparatus;

a content reception portion to receive content data selected in the other information processing apparatus based on the information contained in the metadata and transmitted from the other information processing apparatus;

a content acquisition portion to acquire the content data from the content storage portion based on the information contained in the metadata; and

a control portion to control the content playback portion to play back the content data transmitted from the other information processing apparatus and the content data acquired from the content storage portion by the content acquisition portion.

7. A music distribution system comprising a distribution server for distributing music and an information processing apparatus for playing back music, connected to the distribution server over a network, wherein

the information processing apparatus includes:

a music storage portion to store music data;

a music playback portion to play back music data;

a metadata acquisition portion to acquire metadata describing information about the music data being played back in the music playback portion;

a metadata transmission portion to transmit the metadata acquired in the metadata acquisition portion to the distribution server;

a music reception portion to receive music data selected in the distribution server based on the information contained in the metadata and distributed from the distribution server;

a music acquisition portion to acquire the music data from the music storage portion based on the information contained in the metadata; and

a control portion to control the music playback portion to play back the music data distributed from the distribution server and the music data acquired from the music storage portion by the music acquisition portion, and

the distribution server includes;

a music retention portion to retain music;

a metadata reception portion to receive the metadata describing information about the music being played back in the information processing apparatus from the information processing apparatus;

a music selection portion to select the music retained in the music retention portion based on the information contained in the metadata; and

a music distribution portion to distribute the music selected by the music selection portion to the information processing apparatus.

8. The music distribution system according to claim 7, wherein

the music selection portion selects music having the same or similar feature as the music being played back in the music playback portion.

9. The music distribution system according to claim 7, wherein

the music selection portion selects music related to the music being played back in the music playback portion.

10. The music distribution system according to claim 7, wherein

the control portion controls the music playback portion to sequentially play back the music data distributed from the distribution server and the music data acquired from the music storage portion as music having the same or similar feature.

11. The music distribution system according to claim 7, wherein

the information processing apparatus further includes a first music analysis portion to analyze music data to be played back in the music playback portion and obtain information about the music data.

12. The music distribution system according to claim 11, wherein

the first music analysis portion obtains information about a tune of music data, and the metadata acquisition portion acquires metadata containing the information about the tune.

13. The music distribution system according to claim 7, wherein
