Why do some mp3's refuse to delete on my Droid Turbo?

[AC Question]

I have a Droid Turbo 4.4.4, and I want to delete some of my sister's crappy songs on my phone. So I went to my music player (GoneMAD), and clicked delete. Unfortunately, they didn't delete. So I went to ES File Explorer and they didn't delete there either. I got the message "Operation Failed" (when I tried to delete an entire album) or "songtitlehere.mp3 can't be deleted" (when I tried to delete individual mp3's). So I plugged it into my PC, went to File Explorer on there, highlighted the songs I didn't want, and hit delete. They disappeared, so I just assumed they were gone.

That is of course, until I went to GoneMAD again and saw they were still there. So I went to ES File Explorer again, and alas, they are still there and cannot be removed. This is driving me up the wall, so I went to Google and everyone else's situation seems to be different from mine and the solutions don't work. How do I get rid of these damn things?

Welcome to Android Central! What directory are the songs in?

I'm sorry, but I'm a bit of a nub when it comes to this! I'm going to guess what you mean by directory and say its located at

This PC\XT1254\Internal storage\Music

Also it is not all mp3's that won't delete. Should I post the directory to each individual folder?

No, that's ok. Have you already tried rebooting the phone?
