For example, bands like Kings Of Leon and U2. I feel like REAL fans liked them before they were mainstream. REAL fans like their songs that aren't singles. REAL fans like the hits the least. REAL fans know the band's history and how they came to be. REAL fans keep up with their lives.
Well you know what negative thinking?! I think you're just being silly and 'REAL' fans don't exist. There is no hierarchy of music loving and songs are made to be enjoyed. Stop getting caught up with the elitism mentality and just STOP thinking about it so much.
Ignore the overly zealous internet extremists who think they can define what a "true fan" is like. Just stop. Okay? You go on liking what you like without worrying about where you stand on the non-existent continuum you think is there. Alright?
