Systems and methods for reducing the length of music data files having decaying sound patterns are provided. A system and method can include analyzing a music data file including an attack portion and a tail portion. A fadeout range can be associated with the music data file, and a cut threshold of the tail portion can be identified. A modified version of the music data file can be played back. The playback can include reducing sound levels of the music data file in accordance with the fadeout range and ending the playback when the cut threshold of the tail portion is reached.
