Album/Artist unknown for some songs

[Robin_PJ]

So I recently updated my Nexus 6 to Nougat. And this problem has been bugging me ever since. There are some 41 songs in my collection that have their artists and albums show up as unknown on all music players. I've checked the tags, deleted the songs and moved them again to my phone from my PC and it's always the same songs that show up with neither album nor artist. I've also cleared the Media Storage data and rebooted. Interestingly, I also can't seem to rename any of these 41 songs using the secret File Explorer in the Storage settings. But I know they're not damaged files because they work perfectly on my PC. Please help.

I have this problem with one B*witched album. The only album that displays unknown with no album art in every music app however it does display album art on other non Noguat devices fine. It is playable though in any music app.
