i use tag&rename and mp3tag apps, i made a various folder of over a 100 mp3's all had different numbers name non capital letters on some all out of whack so to speak, for that i used tag&rename, it has a preview button that shows folder i chose, then use a mask to remove all numbers like 01 or 1. etc i used this mask %8. %2 save, or just leave them without numbered etc, then use mp3tag in the field you will see filename path tag title artist main screen, choose your order it can capitalize any and fix file names as well, also remove cover art and replace with whatever you want, all of them at the same time, i had to fix my few thousand mp3's flacs etc, as some players could not recognise certain tags or order.
