these commercial hits usually tend to have a lot of writers, producers, and music agencies that control how they're distributed. the artist actually ends up getting paid dust in royalties, the main disadvantage for indie artists is that they don't have a huge label backing them up in terms of promotion and budget. but if they luckily get a hit, they get to enjoy more royalties from that song than a mainstream artist would.
