The audio Revelator delivers to YouTube generates an Art Track which consists of the sound recording, the album art, and metadata about the recording, such as its title and artist name.
The Art Track will be automatically delivered to:
A) the Artist - Topic channel or
B) the Various Artists - Topic channel
Art Tracks will never be uploaded on the artist channel.
If you want Art Tracks to be featured on the artists channel, you have to create videos and upload them manually on the artists' channel.
