I don’t use WMP, if I could uninstall it I would. I don’t even use Groove. Same with IE or Edge (I use Chrome exclusively, to include the extension to route any searches to Chrome/Google) Occasionally, I use MusicBee on my PC but I am fairly certain I never opened the files in it; they are located in a separate folder that MusicBee does not scan. On my phone I use gonemad media player but only copies of the tracks were moved over there. I tried replicating the issue by running them through both programs and nothing happened. Fortunetly, I have not found anymore and it seems to have happened to only a few. In addition, Picard is such an excellent program having to re-tag is a relatively painless process in which a great deal of the usual tedious work is alleviated.
Perhaps, knowing how obnoxious WMP is, somehow it could have gotten ahold of them, that would mean it searched my whole hard drive because these were located on my desktop. If there was a way I could lock it in an airtight container and leave it at the bottom of the sea that still wouldn’t be enough.
Thank you for your reply and warning to further defend my music from freakin WMP!
