Sony VGC-RA810G - Manual (Page 210)

Why aren't the song information edits I made using SonicStage software shown in My Music?
If you record a song in OpenMG ATRAC format and make edits, such as title, artist, or genre, using SonicStage software,
the changes become visible when the music file is played in My Music. If you make changes to a music file using Media
Center, the changes are not visible when played in SonicStage software.
