Music purchased from iTunes have the composer tag which alongside the composer also includes artist and featuring artist like:
Kozbeats & Maitre Gims
Kozbeats, Maitre Gims & Jul
In both of these examples, only Kozbeats is the composer while Maitre Gims and Jul are Artist and featuring Artist. So the question is how can the composer field be edited to only keep the "real" composer while stripping the artists?
I'm still new to MP3tag but I'm guessing this could be accomplished by the regular expressions, where the syntax could query the artist field for artist and title field for featuring artist and any matching words could be snuffed out from composer tag. It's just a guess though.
Any help will be greatly appreciated.
