If I love someone's music, I stan for them. Success is just an added bonus but not all the artists I stan for are successful. That doesn't make me love their music any less
I started stanning for Beyonce before I knew what sales were back in the DC days, I was like 7 years old.
However, I now stan for both because I love to see that my faves material is getting all the praise it should be getting, but even if her album or w/e flopped, I would still be there and supporting her all the way.
Success & sales are a good bonus, but if you stan solely off sales and sucess then you have a problem.
