There is an artist who is not played on the radio but has a very large fan base. The fans of this artist naturally do the only thing they can do to make up for this lack of radio, and they buy the songs. The concerts of this artist are completely sold out. They give concerts in stadiums, not arenas. So yes, they are demanded artist.
On the other hand, there are the artists who stay on the charts for weeks or months thanks to the money their companies pay to the radios, but find it difficult to sell their tickets at the concerts. I'm talking about arenas and theaters, not even stadiums. Without radio, it is impossible for most of them to even be on the charts.
Then Billboard, which has a very close relationship on the radios, changes the rules in favor of them and doesn't touch the radio payolas. They call it justice, but for whom?
