Ignoring the fact that it will likely be taken down having your account being issued a copyright strike, what you'll probably want to do is open the track with some video editing software, insert an image or background and then render it as a "video"
Be sure to check the audio options as you'll want to ensure it stays CD quality.
Also be aware that youtube applies their own compression so you will never get 1:1 quality compared to CD or other lossless source.
