Thanks for the hint.I've wodered about too if I can live with the
quality loss. I cann say that only if I try.
Well, I've tried to edit the ID4 within XMMS. I can edit this but
without changing the file. Saying this : I edit the tag, save it and
nothing changes.
Could you point me to some of the "lots of tools" you mentioned?
... and what about the time information? It is silly to have a 3 minute
song with shows as days long and even negative duration :( (well, this
could be an ``unsigned int'' issue.

Thanks
