NO. It is called "cover" and covers will NOT get copyright strike because a cover is your property. Remember a "Karaoke cover" will get a copyright strike if the instrumental track is the original track produced by the copyright holder.
I hope that helps.
Are you sure? I heard it's kind of a legal limbo, if you want to make a cover, you have to get the rights for it, if you publish it. But I think as a privat person it is not that strict, I don't think GLEE will bring an action against you.
