Being a confused loner loser allowed him to make incredibly relatable and emotional music. Now that he's a real rock star his music has none of the soul that made it good. Listen to the original Twin Fantasy vs. the redux. They're the same songs and the new ones are fucking soulless. He sings with no emotion and the overproduction/synth-y stuff removes all the feelings of being a dumb teenager with nothing and no one who has no clue what he's doing in life.
