People who heard hit songs before they blew up, did you initially think that said song would get as big as it did?

Back in 2014, I saw the music video for Shut Up and Dance by Walk the Moon, back when it hadn't hit the Billboard charts yet and it had less than 1 million views on Youtube. I remember thinking that it was a super catchy song, but I never expected it to become a big hit since it was a lot more rock-ish than most of the songs that were popular at the time. Come 2015, the song blew up big time, and I was in absolute shock that a song that I thought only me knew about was so popular now!
