You do not ask questions about a Ford Mustang at a Ford truck dealer... and you do not ask Premiere Elements questions in the Premiere Pro forum
I am no longer active in the PE forum, but there HAVE been past discussions about iTunes problems, so the people there DO have answers
iTunes music problem https://forums.adobe.com/thread/1775961
I have success with MP3 files, but Apple WAV files probably work too. If you can get your iTunes track into a MP3 format it should be easy. That part has to be between you, iTunes and whoever owns the copyright.
Once you have a protection free audio file like an MP3, you bring it into the project exactly like you do a video file. In other words, you use the Add Media process. You will then see it in your project assets along with the video clips.
You can now add the "tune" to any of the audio tracks exactly like you would a video clip. If your video is on track 1, track two should work fine.
I don't see where you've asked this question on this forum before -- but no matter.
Note that a lot of iTunes music includes very strong copy protection that can prevent your using it in a video editing project. Trying to will throw up an error code.
You don't say anything about what you have tried or what the nature of your problems are. But along with Bill's suggestions, I absolutely recommend you convert any iTunes music or MP3s to WAV files before you try to use them in Premiere Elements. You can convert MP3s to WAVs using the free download Audacity.
Then you just select Add Media/From Files and Folders.
