my macbook pro gets real slow when using iTunes
I have a Macbook Pro, with 320 hard disk, 320 gb hard disk memory, 4 gb RAM. I think it's about 4 years old. I have over 12K songs in my iTunes library. Every time I open this program, my mac gets real slow and I get the beach ball of death very often. Is there something I can do in the program, or the laptop, or is this time to get a new Mac?
MacBook Pro, OS X El Capitan (10.11.4), 320 gb hard disk, 4 gm ram
