Yes, my previous copies (several in the past) always displayed my album cover art when accessing with my BluOS app and my NAD M50.2. Yes, my update to the NAS drive was a new copy of my Apple Music file from my MacBook Pro. (All of my Apple Music is purchased content or recorded from a CD) So no encrypted Apple Music files (not purchased from the iTunes Store) that I know will not always transfer to a NAS drive.

Yes, I deleted my Apple Music file from my NAS drive in order to update it with a new file which had my more recent downloads which I had purchased from iTunes. Let me see if I can answer your questions as asked. So if you want to save space, first of all, make sure all your artwork isn't taking up lots more space than necessary.Thank you for your response. However, if all those had been converted to PNGs, then I'd expect that to be several GB. The iPod's Artwork folder takes up about half a GB, which isn't a lot considering. Almost all of those have artwork, and a fair proportion of it is high-quality 500x500 from. Its 60GB is practically full with 12895 songs.

(The alternative is to drag it onto your HD, and then drag that file onto iTunes, which preserves the format and size.) I know it's blowing my own trumpet, but I posted a story a while back showing that the most obvious way to copy artwork (dragging from browser window straight into iTunes) will convert it to PNG format, which is often 5x or 10x bigger than the original JPG. It probably depends on how big the image data is. However, this should work with all iPods that can display album art and regardless of Mac or PC format. I have tested and verified this with a 60GB iPod 5G and a 4GB iPod nano that were formatted for a Mac. When I did this on my 60GB iPod 5G that had about 20MB free, I was able to reclaim over 1.5GB (yes, that's GB).

To reclaim that space, simply go into the iPod preferences in iTunes and uncheck the 'Display Album Art' option. Depending on the size of your iPod and the total amount of songs you have on it, this Database can grow quite large. Instead of using the album art that is embedded in the audio file, the iPod is actually using its own database file to store album art. If you're running out of space on your iPod and have an iPod that can display album art, here's a quick tip that can buy you back some room.
