you're saying the MP3 file has "(17)Rock" set as its genre

I don't know if this has any bearing on the conversation, but sometimes when I download (Empeg->Computer) with Jemplode and it writes the ID3V2 tag to the file the genre field comes out as "(-1)"..

Just for the record:
Issue is solved. It was probably due to a combination of a bug in Easytag and the (correct) logic in jEmplode.

I reinstalled jEmplode, updated it to V52, and upgraded Easytag to 0.30c (according to its logs they updated the id3v2.x part)

Now I get these results in the hexdump of the files:
if id3-tag is one of the 'standard' tags, only the numerical code is stored, e.g. "(80)". If it is a non-standard tag, only the text is stored (e.g. "Hollands"). Both situations are handled perfectly by jEmplode, resulting in correctly tagged files on the empeg.
