It goes without saying that you should not be trying to game the system either by playing your music on repeat or paying for artificial streams. You should also not encourage your fan base to engage in this activity.
When working on promoting your music and building followers, be careful who you work with. There are services out there that guarantee streams or playlist placement in return for money. The streaming services have come out expressly stating that they do not work with such companies. Do your homework, understand who you are working with and how they work. It is your music and your career that’s at risk.
