A hit song is a double-edged sword. On the one hand, it can thrust you into widespread acclaim. But on the other, it can pigeonhole you, your audience forever using your old stuff as a metric. Your work progresses, but your fans are stuck in the past. For a great example, remind yourself that “Creep” is still Radiohead’s biggest hit.
For another example, look to MGMT, who had three such songs. “Time to Pretend” and “Kids” especially were already several years old by the time they appeared on Oracular Spectacular. And overall, that synthpop sound wasn’t very representative of that record. If you just look at the neo-psychedelic freak folk on the deep cuts, Congratulations is a faithful follow up.
