Use one of the many MP3 file renamers to put the Artist or such information in the file name or whatever the player uses now. This player does not appear to have open source so my answer is no.
I just bought the Transcend MP330. Although mostly excellent, it has one limitation that I would like to overcome.
It displays ID3 tag information when playing, but does not allow you to choose items based on ID3 (Artist, Album, Title, etc).
Can the firmware be hacked to add this? If anyone can do this or already has, I am willing to pay.
Firmware updater for version 2.15
I have created a low-tech workaround by creating directories at the top level for the artists.
