This has to be one of the dumbest things I've ever heard.
Buy an album because you like it, not because it's popular. No fan can predict a promo strategy, if everyone thought your way, no albums would be purchased until after all of the promo is done. Everybody likes to sit on the internet and play A&R, but at the end of the day, these artists are not recouping off sales and then aren't able to go on tour if they cannot get enough sponsors. And it works hand in hand, if companies don't see you selling albums they are not going to believe that you can sell tickets and merchandise and therefore are very unlikely to sponsor your tour. These artists do what they can to promo their shit without money - it's call social media posts. The music business is a BUSINESS and in business it takes money to make money. If the label is not willing to INVEST in the album, then the album, the promo and the era are dead on arrival.
