A mobile phone with music reproduction function has a reproduction unit that
reproduces
music data and a ring tone which are recorded in a music data recording medium,
and a communication unit 108 that detects an incoming call from outside.
The mobile phone 100 has a control unit that instructs the reproduction
unit to perform a fade-out process of reproducing the music data and to perform
a fade-in process of outputting the ring tone when the communication unit detects
an incoming call while the reproduction unit is reproducing music data.
