For the pro version : Supper tagging ? why not ??
the supper tagging, actually available on the Music Match jukebox, authorize the reconition of the file.
take any mp3. delete all tag (v1 and v2) rename the mp3 like qwerty.mp3
and in Music Match jukebox Plus (who necessit to pay) you make a right click and "supertagging" menu ..it can reconize the mp3, add the picture of the cover, complete id3tags and so on.
The technology is not only dedicated and make by MMJ
there is différent company who make that (for exemple http://www.musicbrainz.org/
it should be great if added to the pro version !
