Are covers of songs on YouTube legal...?

-Are covers of songs on YouTube legal if you play the music by yourself on piano and don't use their recorded music? And also if you don't intend to make money off of it? Just worried about what will happen to my videos. :/ thanks.Recording a copyrighted song and posting it on Youtube without permission is copyright infringement. However, in most cases, the worst that happens is that the infringing recording is removed. Copyright enforcement is so poor on Youtube that there's probably a good chance your recording will never be removed.

So you can do it...but sometimes it is blocked in certain countries...don't know why though.Perfectly legal
yes
