I disagree.
Some artists can have the most amazing albums ever and never sell them and rely solely on singles. Flo Rida, Pitbull, Jason Derulo and the like all have really solid albums but we all KNOW that no one is going to buy them and THEY know that too. So they just release tons of singles and that gets them their sales and coins. There isn't anything wrong with that. Some artists just know that their purpose is selling singles so they stick to that. If it's not broken, don't fix it.
And, let's not even go into the fact that she herself relies heavily on singles to sell her albums. Who knows where she would be without smashes like CIL, BB, Irreplaceable and the like? Singles are really important in order to have a relevant presence to the GP. They base your popularity off of how often they hear your song the radio.
