It is very very slow to load the artwork. Take a very long time "Loading artwork...". And finally it completes, I quit the Music app, bring it backup, it "Loading artwork..." all over again.
My songs are all in my hard drive and they have complete artwork (no need to get artwork from server and in fact I turned off getting artwork from server).
So, this new rewritten app is bad. Like back in old days when we used old version of iTunes, it was pretty bad until many new releases.
I guess Apple quality is dropping. They are like Microsoft and have us to help testing and ironing out their bugs for them.
So sad...
