iTunes goes unresponsive every time i open iTunes
I have a mac book air that i bought less than a year ago. With the new iTunes update i didn't have a problem all day yesterday, now today, every time i open iTunes and try to either play music or edit songs and such, any basic usage, iTunes goes unresponsive. It has done it all day and i have had to force quit iTunes every time. I only have safari and my mail app open and can't understand why its consistently bugging up. Any help would be great, Thanks.
MacBook Air, OS X Yosemite (10.10)
