A first release introduces your music to people who have no history with it. Give them a clear reason to listen, and make the next step easy to find.
There is no useful universal target for how many streams that should produce. The starting audience, the music, the campaign and the available resources all affect the result.
Get the foundations in place
Make sure the music, artwork, artist information and listening links are ready. Give yourself time to check the details before you begin directing attention to them.
Decide how you will introduce the song. A simple, specific idea is usually easier to execute than a long list of promotional tasks with no clear connection.
Look for signs of interest
The first campaign can show you who responds, which parts of the song people remember and what makes them want to hear more.
Take those observations seriously without treating a small sample as a verdict on your career. Early results are information you can use.
Leave yourself a next step
Have something for a new listener to explore: another performance, the story behind the song or a place to follow the next release.
Afterwards, review the work honestly. Keep what helped people connect with the music. Change what did not. The next release should begin with more understanding than the first.
