There are provided a download system and a download control method for portable players, which enable a user to download music data to the portable player by a simple operation, and a storage medium that stores a program for executing the download control method. The portable player includes a storage medium that stores music data having type data. A download device downloads previously stored music data to the storage medium of the portable player. A center station transmits music data having type data to the download device.

When the desired type data is equal to the new type data and the new type data is different from the known type data, the music data transmitted from the center station is stored in a data memory device, and the stored music data is downloaded to the storage medium. Then, the new type data is written as known type data.
