I use copyrighted music in my videos all the time. Of course I use Youtube, and ALWAYS credit the artist.
The reason is that the artist is okay with this ? The song is for sale as an MP3. Via Google Play, I Tunes, and Amazon MP3. Go ahead click on the video, go to Youtube and look at the top right hand corner under the video.
This video I shot has been viewed nearly 8 K times. I haven't looked lately but at one time it was second on the first page when one searched Youtube for the song, Nothing But the Taillights.
(I just checked and my video has slipped to position 8 on the first page...I am good with that, and I hope that it has generated some sales for Mr Blacks wonderful song!)
Keep in mind I produced this video three years ago after buying my first dslr. I was only experimenting with the camera, which in now my backup camera. I upgraded a year ago. :-)))
