BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music search method, and more particularly, to a method of searching for music using metadata.

Recently, various devices for playing music files such as TV, PMP, MP3P, and HHP are increasing in popularity. In addition, because of the expansion of large memory and changes in the way music is bought or purchased, music is being heard in a different environment. One is that the number of music files stored on the device increases. This is a positive aspect of broadening your choice of music, but it can take a lot of time and effort to search for the music you want to hear because of the large number of music files.

Accordingly, techniques have been proposed in which all the metadata or items of categories and subcategories are displayed while using categories such as genres, albums, artists, and the like, while displaying the metadata of the subcategories associated with the selected metadata in association with each other.

U.S. Patent No. 6,928,433 issued to Creative Technology Inc. has three layers of categories, subcategories, and items. When a user selects a desired one of the three layers, the next layer screen is displayed , The first screen is classified, the second screen is divided into small categories, and the third screen is configured to correspond to the item. For example, the user first selects "Artist" on the displayed screen. As a result, the displayed second screen presents a list of artist names. When the user selects, for example, "Kim Gun Mo" from the artist name list, the third screen lists album names related to "Kim Gun Mo". If the user selects "2nd album - excuse" among them, playback of the song starts.

However, the above-described method must select the metadata category before selecting the metadata. For example, to select "Kim Gun Mo," you have to select an artist from the menu and then select "Kim Gun Mo". In addition, since only the metadata selected in the upper category is displayed at the bottom, a wide selection at that stage is impossible. For example, in the album category, you can only find the album of the artist selected in the previous step, and if you want to find another artist, you have to go back to the previous step and select the artist name again.

And it is impossible to listen to only the songs you want to hear. Singers, and albums can not be selected. For example, Kim Gun-mo-3 - Wrong encounter and Mozart-Mozart Violin Concertos-3 symphony can not be selected and played together.

SUMMARY OF THE INVENTION The present invention has been made in order to overcome the above-described problems of the conventional art, and it is an object of the present invention to reduce the number of steps of selecting categories by displaying items of metadata selected or metadata items related to selected metadata on a display screen, The present invention relates to a music search method and a music search method.

It is also an object of the present invention to provide a recording medium on which a program for causing a computer to execute such a method is recorded.

According to an aspect of the present invention, there is provided a method of searching for music using metadata, the method comprising: displaying at least one of a category, a sub-category, and items on a display screen of a portable media player; Selecting one of the metadata of the category or the metadata of the subcategory; And displaying items of the selected metadata or items of metadata related to the selected metadata on the display screen.
