There are two points that you have said that are important.
First, you need quality tracks. Quality tracks are tracks that are similar to what people hear what they love, and most likely all of them are from people who know what they do aka. professionals or at least a really good level (they have the tools, knowledge, and talent to pull those tracks out.)
Second, the traffic and/or connection to already popular topics (games, tv-shows, movies, featured artists, etc.)
Both things you can only have if you are doing it for years, building connections, building repertoire, building your brand & name in the industry. All of it takes a lot of time and effort. And that’s what most people don’t see first. They only see the “end-result”. Like: “That’s the reference…”. But in my opinion, it’s wrong to see or analyze this way. It’s not what other people achieved and what they say what they think what “possible” is. It’s first truly understanding and being aware of what they actually did to get to where they are today and what they have now.
As well, don’t forget that what they did so far maybe worked out pretty well due to the market situation. It doesn’t mean that someone who starts out today or has those goals will achieve it even with putting in the same or even more work into it, due to the fact that the markets are changing very quickly today. For example: What happens if Spotify goes broke tomorrow? Just hypothetical. And most of your attention was there? You worked for years to achieve what others told you they’ve achieved the last 6 years, and suddenly you see it doesn’t work nearly well for yourself.
First, the attention should be only to your main craft and passion. Building your “character”, like in a video game. And in parallel, you’ll see after a while what platform or service, or library, or website goes into the direction that you like most in terms of ROI. aka. you start focusing even more on that one or two.
But before all that you should and everybody else too, of course, answering the most important question: What do you really want? Do you want to make money by making music? Do you want “fame”?
What I actually mean by that is that people who start out or are about to take the next step in how to make a business in that business are focusing too much on the money game. And that’s why I believe so many are quitting after a while as they look at others what they “promise” them, not really, but that’s what all people see $$$ and after a while realize that they never achieve those numbers or clicks, or views, or whatever. And then they ask why it doesn’t work out. And when you look at it, you quickly see what the issue is: lack of focus, lack of persistence, lack of passion, lack of durability, lack of social interaction, lack of thousands of other components that are required to get to that level everyone wants to “achieve”. Start with that first, and no matter the platform or website or whatever the market is telling you there is, you’ll get it sooner or later with that intention.
