Abstract: An information reproducer (1) includes a element (15) for reproducing content data, a first setting element (20) for setting first loop reproduction unit data, a conversion element (20) for generating conversion data by dividing or elongating/contracting a plurality of unit beat data each corresponding to one beat included in first loop reproduction unit data, a second setting element (20) for setting second loop reproduction unit data where (i) the reproduction period is substantially identical to that of the first loop reproduction unit data, and (ii) a beat appears at a timing synchronous with that of a beat appearing in the first loop reproduction unit data by combining the conversion data, and a element (20) for controlling the reproduction element to perform loop reproduction of the first loop reproduction unit data and the second loop reproduction unit data.
