    Abstract: A method and apparatus for reproducing a first part of music data having a plurality of repeated parts includes a method and an apparatus allowing a user to listen to more songs including the repeated parts by searching for a boundary between the first and second parts of the music data having the repeated parts via simple frequency analysis, marking information indicating the found boundary, and reproducing the music data until a part indicated by the marked information is reached. Accordingly, music reproduction satisfaction increases since an inconvenience of manipulating the apparatus for each song is lessened and more songs having different patterns are played.
