The new walkman actually does not use the horrible Sonicstage
software that it's previous products used. You can play both ATRAC
and mp3's on the walkman. An ATRAC to mp3 file converter is
included on the software CD that comes in the package. Since the
walkman is mp3 capable, you are indeed able to download songs onto
it (assuming the songs you download are mp3, wma, ATRAC, or another
compatible format).
