DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic music selection system, an automatic music selection method, and a storage medium for determining the playing order of a plurality of music pieces.

[0002]

2. Description of the Related Art In recent years, it has become possible for a music reproducing apparatus to reproduce a large number of music pieces continuously by being connected to a mass storage device or a network. Therefore, when the user performs the continuous reproduction of the music, the user selects the music according to his / her preference, reproduces the music in a prescribed order, or performs the continuous reproduction of the music by a random reproduction function or the like.

[0003]

However, in such a conventional music selection method, when performing reproduction in a prescribed order or when using a random reproduction function, the music is selected in consideration of the user's preference. There is a problem that cannot be reproduced. In addition, when selecting a song according to one's own preference, the user must manually select a song from a large number of songs one by one, which is very time-consuming and requires a lot of listening. There was a problem that I got tired of it and had to select songs again.

An object of the present invention is to provide an automatic music selection system and an automatic music selection method for automatically selecting music according to the user's preference.

[0005]

According to the first aspect of the present invention,
An automatic music selection system for performing music selection for playing music in a predetermined playing order, wherein the database device stores music information relating to music (for example, the database device 3 shown in FIG. 1).
0), input means for inputting music selection conditions (for example, the input unit 202 shown in FIG. 3), and a plurality of pieces of music information stored in the database device based on the music selection conditions input by the input means. Song information extracting means for extracting song information (for example, C that performs the process shown in step S105 of FIG. 5)
PU101), and a performance order determining means (for example, a step shown in FIG. 5) for determining the performance order of a plurality of music pieces based on the music information extracted by the music information extraction means and the music selection conditions input by the input means. C for performing the processing shown in S107
PU101).

According to the first aspect of the present invention, there is provided an automatic music selection system for performing music selection for playing music in a predetermined order of performance, comprising a database device for storing music information relating to music, and input means. A music selection condition is input, a plurality of pieces of music information are extracted from music information stored in the database device based on the music selection conditions input by the input means, and a plurality of pieces of music information are extracted by the performance order determination means. Based on the music information extracted by the extraction means and the music selection conditions input by the input means, the playing order of the plurality of music pieces is determined. Therefore, if the music is reproduced according to the determined playing order, no labor is required. In this way, it is possible to easily play a plurality of songs continuously and enjoy them. Also, unlike the performance in the conventional prescribed order or the performance by the random reproduction function, the performance order is not fixed to one pattern, so that the problem that the user gets tired of listening several times is eliminated.

Here, the song information includes, for example, the title of the song, the name of the singer, the time of production of the song, the tempo of the song, and the genre of the song. Other information may be used. It may include a plurality of pieces of information.
