In less than a month, New Jersey–based YouTuber and “vocalist extraordinaire” Jon Sudano went from zero subscribers to nearly 207,000. His swift ascendance is attributable to his unprecedented style of covering songs: only singing Smash Mouth lyrics over pop hits. After his first video, a cover of John Lennon’s “Imagine,” made it to the front page of Reddit, Sudano’s videos have been racking up millions of views.
