Q: How can I get rid of duplicate songs in iTunes?

I've been struggling to get rid of them for some time now. The only way is to do this one at a time. I was "hoping" with the new update/version or whatever you want to call It, you can just select by click>drag>and hit Delete. I mean c'mon! How easy would that be right? Most are on the Cloud...

Nope!

Any suggestions? I'm running a Mac Pro Mid-2012 on Maverick using whatever is the newest iTunes....

Thanks
