To provide a device for music in which prior audition of music data is made possible prior to a writing by disk-at-once.

A CPU110 displays an input screen 153 into which information related to a plurality of music data that are writing objects to a CD-R is inputted, receives the information inputted onto the screen 153 by the operations of various operating buttons and registers (a pre-reproducing table) the information for pre-reproducing the plurality of music data prior to a writing operation to the CD-R. Then, registered information is referred to and the plurality of music data are reproducible as writing objects prior to conducting the writing operation. Thus, prior audition of the music data is made possible prior to a writing by disk-at-once.
