Let's talk about the strategy first, Spotify works like the social media network, and you have to be active, to get your audience. There are a lot of tracks are being released every week and you need to work hard and constantly to get your audience's attention.
We will talk more about this later but I want to explain the way the algorithm works in 90% of cases - if you will look at the curve of the track plays you will see that the highest activity was during 4-6 weeks, and then it goes down, so what you need to do is to release one more track and pick up your activity again. It will be really brilliant for your profile if you can do this every month or two.
