Ey, the best youtuber in the planet is now an steemite! I think it does very good to have music & fun in the "blockchain", since its becoming to serious lately around here.
What you can do to get your almost 4000 followers into steemit, is to publish first the video as unlisted in youtube (can only be viewed if you have the link) and post the link as a new article on your steemit blog. Even better if you add some description to it (and not just the video). After 24 hours you can make it public in youtube to let also the youtube community see it.
Great first post and welcome. I can not wait to see the next one here!
