Thank you Sebastian
but, well, this i undertood. That is the way to do it that i didn't...
In fact i would somehow like to give him a pseudo freedb data base where he can pick up the tags for each file we have in common.
if it is by exporting the tags, i would like to know the way to write the script so i can give him :
filename - genre - artist - album - date - track - title
and the way he can put them on his files, knowing his filenames are different (oftenly finishing by "Audiotrack XX").
if it is by local freedb, i tried to do it but i am asked for a freedb id... beuh... how could i know ? I tried with a ID given by the internet freedb once, but when i tried to enter it to local, it replied he could find matching result...
Must be a big something i don't get in this, isn't it ?
Help me if you can (like the other one said)
