Capture sync in a debug log (step 4b) and attach it to a Support Ticket: http://mediamonkey.com/forum/viewtopic.php?f=12&t=69

USB and MMA 1.3.2.0822. I now have 3 indications for every song in MediaMonkey Windows, i.e.,
Shadow Captain
Shadow Captain
Shadow Captain
yet the actual song is only in my music folder once.

It only shows the song once in WWA.

So the sync clears out the card in the phone, rebuilds the music library on the card, and then adds the the same name back to the Laptop so it shows up 3 times.

Are you doing a wifi or USB sync and do you have MMA installed?

I have MMW 4.1.21.1875 and MMA on my Samsung Galaxy S7. I have a 22 GB library of music. I followed the Sync MediaMonkey with an Android Device Wiki to the letter. I synced to a 32GB card with nothing else on it. When I ask MM to sync again a few days later, it shows 9 GB empty and tells me there is not enough space to sync.It then says do you want to delete old files to make space? I answer yes and it apparently deletes the entire library and then re-installs the library. This takes almost an hour. Nothing has changed on the music files, they are the same files as in the original sync.
