Hey @gj0 just keep in mind, posting a youtube link without any original text /description may be illegal in most countries because you are earning from it. BUT If you do a review of the song in your own words along with the video, it is perfectly fine. It doesn't have to be long. But some original text is better than none. Here is a post on how to do a review.
