Hi guys, So i've managed to get all my music files fully updated with album art by using the 'Get Album Artwork' feature in iTunes. Everything looking tip-top and complete. I can see the album artwork in iTunes and on my iPhone Music app no problem. But, i've transferred some of my music to my mum's Galaxy S5 and found the majority of the music does not contain any album artwork, even though I can see it in iTunes. Upon further investigation, checking out the mp3 files in Finder via Cover Flow reveals the standard non-album artwork cover. I'm guessing that iTunes doesn't actually save/attach the album artwork to the mp3 file itself but retains it in some secondary linked database/cache? I'm really confused and would really appreciate some help. Thank you!
