Whether it be iTunes or Apple Music it is still the absolute WORST music management system out there. Quite the embarrassment for Apple IMO. Something this simple 14 year middle school kids write code for in school that works better. I still to this day have problems with artwork dropping, not carrying over to (10 year out dated syncing) to iPhone). Song tracks randomly drop, links to music drop. Oh and do not do something as simple as trying to move to another hard drive.....or reimport music when everything does get messed up as half the art work will not carry over or will change. All this on LEGAL music I OWN that is not available on apples streaming service. Some of these are million selling albums that are not rare and easily identified. Ironically anything bought or streamed from Apple NEVER has any issues....I could go on and on but I just got upgraded my hard drive and my whole library got trashed trying to move it to the drive and sync again to my phone so I am rebuilding once again artist by artist, downloading all the messed up/missing artwork as I have now become accustom to. I would LOVE to sit Craig F down and go through all this amateur hour stuff.......
