Sorry my bad I meant 4.1.15.1826 and above.

This appears to have fixed it. I will keep en eye on it.

This is the problem zou need to update to latest MMW 4.1.15.1828 and above to make things working.

For the record, if I sync via USB, and everything looks fine (all album art), THEN sync wirelessly, it will overwrite the "good" USB syncs, removing the album art from them.

I hit "Sync now" (wirelessly) from MMA version 1.3.0.0664 and MMW 4.1.14.1806. Still missing a bunch of album art that shows up fine in MMW, and shows up fine in MMA if I sync via USB instead of WiFi.

I noticed that most artwork sync issues are fixed in latest betas.

Can you be more specific on steps and MM versions you tested?

Any News ???

Has anything been found about this issue?

Thank you for looking into it. Just for the record, I have re-synced many, many times now, trying to figure out the issue.

Hi,
I'm escalating to see if log showed something, but unfortunately I could not replicate behavior in both MMA 622 nor Internal MMA 1.3.0.656 Beta.

Will let you know after log analyze, but I would suggest due the number of changes you consider resync tracks with missing Album Art.

Has anyone looked into this, or looked at the log I sent in...?

I am having this same album art issue. ALL of my album art syncs perfectly via USB, but some of them are missing with WiFi sync.
It can't be the "multiple album arts per album" issue mentioned above, because it is an issue for albums that I only have one song from...that song has no album art. (I did check that, though, just in case.) It doesn't only apply to albums with various artists (like the OP described), but songs off of albums from a single artist.
It works perfectly fine with USB sync, but as soon as I do WiFi, it replaces the album art (placed there by USB sync) with the grey MM symbol. It is consistent in which songs have the issue...it's always the same ones. I just can't find out WHY.
I sent a log about it: JXACAR3UQJ

I've been following this thread but i haven't seen any resolution or ideas of what's going on with albums syncing incorrectly. It has to be some mediamonkey bug but not with syncing because one thing i found out after trying many of the suggestions on this forum is i opened the Music app that comes with my Samsung phone and all the songs and their albums are displaying correctly, i have tried the same with my daughters phone and same thing. the phone music app reads the files correctly. I know it is not only android related because i have tried syncing to and Iphone and the album art still gets messed up. I normally sync from a playlist and i have made sure no album art is missing on said playlist. Just trying some of the theories on the forum. still same results mma says updated some files but nothing happens, sync problems are occurring wired or wifi. My theory and i'm not in any way an expert seems like the problem is with the refreshing of the lists on the app memory or the play now that stops the app from refreshing the files updated. Any other ideas? I love MM and i have them on my PC as well as all my family phones, i bought the pro license as well.

As said, MMW creates the Artwork cache on sync for MMA to display Artwork. MMW takes Artwork from 1 file on the Album for all synced files on the Album. So Artwork needs to be in order in MMW for MMA to show the correct Artwork.

With all the modifications you've made you may want to start with a fresh sync between MMA and MMW so MMW correctly updates the MMA Artwork cache.

Having checked through music library the pc - most of my albums don't have an artwork file, so the artwork must be embedded as a tag.

So I have:

1. Albums which were showing the wrong cover art had a art file in the folder. This has now been deleted but on sync, MMA is picking up the previous wrong cover art - not sure where it is finding this from if he file is deleted?

2. Albums which have always been showing the right art, do not have an art file, the cover art is embedded - so is MMA reading this somehow?

3. As a test, I added the album art as a file to the folder via MMW and synced, MMA still does not pick it up - does i need to be called something else apart from 'folder.jpg'?

Apologies if i'm missing something obvious.

Thanks for all the help!
