I have one problem! (Sorry my English)
When I convert Filename ("ACE OF BASS - Top 1000 Pop Hits Of The 80's - 04 - The Sign.mp3") to Tag, I can't demerge it to Title, Artist, Album, Track! How I do it?
Or, how I replace "ACE OF BASS - Top 1000 Pop Hits Of The 80's - 04 - The Sign" in Title, Artist and Album colonn with "ACE OF BASS" in Artist colonn, with "The Sign3" in Title colonn, with "Top 1000 Pop Hits Of The 80's" in Album colonn?

"Convert \> Filename - tag"
Format string: _%artist% - %album% - %track% - %title%_
