PROBLEM TO BE SOLVED: To provide a music reproducing device of a simple and inexpensive configuration capable of reproducing two pieces of music simultaneously by sharing the processing load between a CPU 18 and a decoder 22. SOLUTION: A plurality of compressed music data are recorded in a memory card 12. The CPU 18 reads two pieces of the compressed music data from the memory card 12 in a time-division manner in response to the operation on an operation keyboard 20, and transfers them to the decoder 22 of a DSP configuration. The decoder 22 decodes the compressed music data for each music given from the CPU 18 in a time-division manner, and inputs one of each decoded music data to a D/A converter 24 and inputs the other to a D/A converter 38. The analog music signals converted by the D/A converters 24, 38 are amplified by the audio amplifiers 26, 40, respectively, and thereafter, they are inputted to stereo-compatible headphones 30, 40 via the output terminals 28, 42 and thus the simultaneous reproduction of two pieces of music can be realized.
