How can I use iTunes songs in my PowerPoint presentation?

I burned a cd to my laptop to add to my iTunes playlist a while back and now I’m wanting to use a song from that cd that’s now on my playlist to use on my PowerPoint presentation but when I’m in PowerPoint and I select the option to upload a song it only lets me upload a song from my computer. It doesn’t give me the option to upload it from iTunes and I’m not able to copy that song from iTunes to my desktop so I could then upload it to PowerPoint. Does anyone out there know how I can get that song from my iTunes playlist to my PowerPoint presentation? I’d greatly appreciate any help anyone can provide me. Thanks
