Apparatuses (1) for creating lists of multimedia files are provided with memories (2) for storing features of first and second multimedia files defined by first and second codes and with comparators (3) for comparing a characteristic of a third multimedia file with characteristics of the first and second multimedia files and with allocators (4) for, in response to first / second comparison results, allocating the first / second code to the third multimedia file. The list of multimedia files comprises multimedia files defined by same codes. Features may be identifications, titles, names. Multimedia files comprise audio, video, songs, movies. Codes may be classification codes. Characteristics may be tempos, rhythms, timbres, instrumentations, beat strengths. The comparators (3) may comprise calculators (5) for calculating distances between characteristics of the multimedia files. The first and second codes for the first and second multimedia files are generated in response to user actions or search engine actions. |
