Abstract
A method and apparatus prevents duplicate and redundant data of song information from being stored in a media player by checking a category and duplication of meta data associated with a song that is received through digital broadcasting. The method and apparatus prevents the unwanted meta data, such as a station name, channel number, station frequency, specified in advance or other redundant data such as the one already stored in the media player from being stored in the media player. Thus, when listening a song from a digital radio broadcasting station, the method and apparatus enables to effectively collect the meta data in the media player that are necessary for later activities such as purchasing the music file of the song.

A method of storing song information in a media player, comprising the following steps of:
- presetting a list of information in a memory in advance that indicates categories of song information that should be stored or not in a media player;
- checking whether a user activates a record button or equivalent thereof to instruct that song information of a song that is currently being played from a digital radio broadcasting station should be stored in the media player;
- retrieving the song information that is a group of information of the song that has been played at the timing of the user's instruction;
- comparing a category of the song information retrieved with the preset category of song information stored in the memory, thereby determining whether particular song information is necessary;
- and
- storing only the song information that is determined to be necessary in the media player while deleting the remaining song information.
