Re-analyzing All Tracks

Regarding USB 3.1 issues:

I used to carry mid range small sticks and experienced major problems with NXS2 units. These sticks worked perfectly in any other player but for some reason the latest genration players seems a bit picky. I blame cheap controller circuits.

After this post I got a pair of Samsung Fit Plus and experienced no problems whatsoever. But since the price point for Sandisk Extreme Pro sticks have dropped recently I highly recommend investing, they are lightning fast!

Thanks.  Of note - This has occurred on the NXS2 as well as a different, older model CDJ.

@Ikah > Leave only the APE box checked, and run the tool to remove the APE tags:

Thank you. However, I still have no concept of how to navigate the Mp3tag application and I'm struggling to find a basic tutorial or online guide.

Have you been on the Website of MP3tag?

I believe I have it figured out.  Running the application now on essentially my entire library, following Pulse's example above.  

Of note though, upon adding my entire iTunes library as a directory, I could see after the initial reading of the directory, that there were only a few APE tags in the library, less than ten probably.  More importantly, none of these ten or so tracks with APE tags, were songs that had been imported to my Rekordbox library, or ever on the flash drive in question.
