Abstract
In a karaoke apparatus for playing a karaoke song designated by a request, a first storage rewriteably stores a plurality of song data files corresponding to a plurality of karaoke songs to form an extendible library which can be updated. Further, a second storage permanently stores another plurality of song data files corresponding to another plurality of karaoke songs to form a fixed library which cannot be update. A directory table recodes a classification of each song data file classified to one of the extendible library and the fixed library. A storage selector responds to a request for addressing the director table to check a classification of a requested song data file, and for retrieving the same selectively from one of the extendible library and the fixed library according to the classification. A tone generator processes the retrieved song data file to sound a desired karaoke song designated by the request.
