Noo, not on the computer. On RockBox.
I am looking for something to take advantage of the metadata on rockbox, I really thought there would be something out there but I can't seem to find it. Perhaps if there was a plugin player for it, where it'd load the files you already have on there and it could use that data. Most of my music is FLAC so I just ported everything over to a folder where everything is sorted by file names. Unlike where as in the iPod firmware or the software mentioned about, it'll use the metadata for the sorting out.
