I always wanted to know, where does majority of rappers money come from? Take someone who just started making music, where does his money come from and how do artists make money from making music?

I've been battling with the idea that when you are marketing something, your goal should be to select a audience you want to target, get your product seen by them as much as possible (THE MORE THE BETTER), and have it seen in as many different ways as possible. I've noticed that the things that I pay attention to, from a consumer stand point, are usually the things that appear in my face multiple times in different ways or by different people. When it comes to me finding out about a album release, a new brand, a new product, a new trend, etc. It's like this because I know how easy it is for a company to slap a logo on a shirt lay it on a white background and pay money to get ONE placement. So my mind tunes out the stuff I may see once or maybe twice, but ones its something that I keep seeing then there becomes a halo effect around it. I add the point of variation because if it was the same picture or video i kept seeing then i would just think its just an ad, it would still stick out, but it would still just seem like another ad, as oppose to if I saw the same product or whatever it is but in different scenarios, different photoshoots, different interviews, different formats. Especially if I'm starting to see memes about it then I'm not going to think this is just another marketing campaign I'm going to think its actual experience I'm going through at that time. Just remember the Stanley Cup thing.... I mention this because I feel that there is gold in getting people sold on something before you even ask them to pull out their credit card, and I want to know if there is anyone else who feels this way to?
