There are provided an information processing device, an information processing method, and a program capable of suppressing concentration of recommendations in some contents and recommending a content even to a user having little history information by the CF method. Step 11 detects a user A for which a music composition is recommended and another user X having most similar history information. Step 12 detects a music composition owned by the user X and not owned by the user A. Step 13 identifies a cluster of each cluster layer to which the music composition "a" belongs. Step 14 extracts a music composition classified to be common to all the identified clusters as a recommended candidate. Furthermore, step S15 selects one music composition having cluster information most similar to the music composition "a" among the recommended candidates. The music composition thus selected is recommended to the user A. The present invention may be applied, for example, to a content sale site established in the Internet.
