Music Reproduction Device, Method, Storage Medium, and Integrated Circuit

A music reproduction method for reproducing data of a musical composition selected from a plurality of musical compositions stored on a storage section, the music reproduction method comprising:

• an attribute information storing step of storing attribute information, which is information relating to the data of the musical composition, on each of data of the plurality of the musical compositions stored on the storage section;
• a reproducing step of reproducing the data of the musical composition stored on the storage section;
• an operational information obtaining step of obtaining operational information corresponding to a user's operation which represents an instruction on an action of the reproducing step;
• and
• a controlling step of selecting the data of the musical composition to be reproduced by the reproducing step, wherein
• the controlling step includes a selection condition calculation step which changes relative merits of the attribute information relating to the data of the musical composition in accordance with details of the operational information obtained by the operational information obtaining step during the data of the musical composition being reproduced by the reproducing step, and then calculates, based on the relative merits of the attribute information, a condition for selecting the data of the musical composition to be reproduced by the reproduction step.

A storage medium having stored thereon a music reproduction program executable by a computer of a device for reproducing data of a musical composition selected from a plurality of musical compositions stored on a storage section, the storage medium having the music reproduction program stored thereon causing the computer to execute:

• an attribute information storing step of storing attribute information, which is information relating to the data of the musical composition, on each of data of the plurality of the musical compositions stored on the storage section;
• a reproducing step of reproducing the data of the musical composition stored on the storage section;
• an operational information obtaining step of obtaining operational information corresponding to a user's operation which represents an instruction on an action of the reproducing step;
• and
• a controlling step of selecting the data of the musical composition to be reproduced by the reproducing step, wherein
• the controlling step includes a selection condition calculation step which changes relative merits of the attribute information relating to the data of the musical composition in accordance with details of the operational information obtained by the operational information obtaining step during the data of the musical composition being reproduced by the reproducing step, and then calculates, based on the relative merits of the attribute information, a condition for selecting the data of the musical composition to be reproduced by the reproducing step.

An integrated circuit which is used in a music reproduction device including a musical composition data storage section for storing data of a plurality of musical compositions, and an attribute information storage section for storing attribute information, which is information relating to data of a musical composition, on each of the data of the plurality of the musical compositions stored on the musical composition data storage section, the integrated circuit comprising:

• a reproduction section for reproducing the data of the musical composition stored on the musical composition data storage section;
• an operational information obtaining section for obtaining operational information corresponding to a user's operation which represents an instruction on an action of the reproduction section;
• and
• a control section for selecting the data of the musical composition to be reproduced by the reproduction section, wherein
• the control section includes a selection condition calculation section which changes relative merits of the attribute information relating to the data of the musical composition in accordance with details of the operational information obtained by the operational information obtaining section during the data of the musical composition being reproduced by the reproduction section, and then calculates, based on the relative merits of the attribute information, a condition for selecting the data of the musical composition to be reproduced by the reproduction section.
