A song data reproduction apparatus has a storage for song data composed of performance data and order information. The performance data represents a content of a music performance and contains reproduction limiting information for limiting a reproduction state of the music performance. The order information indicates either of a purchase or a preview associated to a usage right of the content of the music performance. A usage right identification section refers to the order information of the song data containing the performance data to be reproduced, for identifying the usage right of the content of the music performance in terms of the purchase or preview. A limiting information read section reads the reproduction limiting information from the performance data when the identified usage right indicates the preview. A reproduction control section controls the reproduction state of the music performance in accordance with the read reproduction limiting information.
