iTunes is a NIGHTMARE

ok so they have now gone back to old school where iTunes is what it was -

now however since the latest update IT NO LONGER CLOSES when i say quit ...

running the latest iOS on a Mac mini with 16 gigs of ram ...

i have to force quit - which will take 30 minutes to open the next time i go to open

as it needs to check the library ....

by which point i no longer care and have to force quit cause now i am done with this UTTER NIGHT MARE

they have created ....

HOW DO WE FIX THIS LATEST BUG ?
