Artist's style usually remains the same
"Adele is great. 'Rolling in the Deep' is fantastic!"
"I used to like Adele. Then she got famous so I stopped liking her." This is not the first time I have had a conversation about an artist or band where the other person admitted their newfound detest for a once-beloved musician as soon as they gained popularity.
This illustrates to me what I like to call the "popularity complex," or in other words, a sudden detest for an artist the second they become mainstream. People may do this for a variety of reasons: such as to protest American-consumerism, or to simply make a statement about how they feel about popular culture. All of these reasons to me, however, are ridiculous.
Instead of feeling ashamed of a singer once they become a regular on WNOK, be proud that you discovered them first. You would not stop eating your favorite food if suddenly everyone else liked it too. The same thing goes for music. Embrace the fact that you were at the beginning of something great. Do not abandon it.
Loving mainstream popular music, especially if the star in question was once obscure, does not make you a sellout. You can still maintain your adoration for a once-unknown band, even if they now top the Billboard charts.
