Demlo is a music library organizer. It can encode, fix case, change folder
hierarchy according to tags or file properties, tag from an online database,
copy covers while ignoring duplicates or those below a quality threshold, and
much more. It makes it possible to manage your libraries uniformly and
dynamically. You can write your own rules to fit your needs best.
Demlo can address any of these recurring music library issues (and much more):

• Fix the lack of folder structure.
• Normalize tags, fix their case, chose which tags to keep and which to discard.
• Handle lossy and lossless audio differently.
• Handle mp3 id3tags hell…
• Handle multiple covers, whether embedded and/or external, resize covers,
  discard bad quality ones.
