I've read all related articles on the wikia about the issue, but I still feel a bit uneasy about a solution so I hope someone can help;;

I recently covered Mafumafu's Yume no Mata Yume. I've used his instrumental that was provided on piapro. As many said, if they provided an intrumental, it's most likely an okay to allow people to use it, and I have also left a comment to inform that I'd be using it and also thanked him for it! But when I uploaded it to YT, I got a copyright from NBC jpn which Mafumafu is signed to. So I can't use the track what so ever;;

I was wondering if I should try to email Mafumafu about it and ask for permission unless anyone says otherwise that maybe I should just avoid uploading it in general;; (I know some Japanese in general, just my grammer and vocab may be a bit wonky.) I wouldn't want to bother him if it was unnecessary. I just wanted to upload the cover to celebrate his birthday... yeah. I just got back to uploading covers again and wanted to start uploading again. But the comeback was a copyright flop haha.. Please send some advice over ><
