copy iTunes library to dropbox
My iTunes library was a mess after an iTunes update. I believe after days of work including copy cds again it is now back. However I don't know how iTunes works in keeping my personal cds and cds I created along with purchases from iTunes so before I do anything else I want to back up my iTunes library on dropbox. But do not know how to do this. Can someone point me at instructions?? Thanks so much
iMac, OS X Yosemite (10.10.3)
