No, not quite.
First step is you need to sign up with a Music Distribution Service like TuneCore, CD Baby, DistroKid, etc. (those are 3 of the most popular ones, and I researched them a couple years ago and found DistroKid to be most cost effective, more rights to you, and less nicke-and-diming with their fees).
You have to use one of these services that partner with Apple (and others) to get your music on their platform.
THEN - yes, you can create your Music Artist profile and use that to manage the music that you publish there - adding your artist profile, artist pics, add lyrics to your music, etc., etc.
That’s why I said once you set up with a TuneCore or DistroKid - it’s just as easy to publish your music to multiple streaming services all at once… No need to be selective. Doesn’t cost anything extra…
