SonicStage allows owners of older and specific walkman models, which are notably incompatible with other music software, to properly sync music collections properly onto their devices. The software differs from other music players given that it is intended for walkman models. SonicStage can also play a wide variety of audio files on your personal computer, including mp3 and wav. The product is similar in function to iTunes and other available music players and can be used to download and transfer mp3 files onto your walkman. SonicStage is a program developed and distributed by Sony for use on their walkman models.
