Question

My entire song list duplicated for some reason. Do I have to delete songs individually (take forever), or is there a way to do it all at once?

Answer 1

I had the same problem.  Had at least 3 of each song in my library...  Here's how I fixed it.
Go on iTunes to your library
Hit Shift and click on View
Scroll down to "show exact duplicate items"
the list will give you all your duplicated songs
Click at the top of the "date added" Column to sort by date added.
Even if it all happened the same day it will group your whole library by date and time added. 
The time is the key...
You can start at the begining of you list and scroll to the last song that was added that day and time frame.
Everything after your last song is duplicates.
Highlight the first song hold down shift and scroll down to the last song... 
Once they are all highlighted you can hit delete and send them all to the recycle bin.
It took me a while to figure it out but it works
