24. Carly Rae Jepsen "Call Me Maybe"
Producer: Josh Ramsay
This was the song that you could not escape this summer. Statistically, it's the most successful, with nine consecutive weeks spent at No. 1 on the Billboard Hot 100 chart. The fanfare is more than justified. Jepsen's cute storytelling and innocent vocals are difficult to dislike (even after the 678th listen), and from a production standpoint, those strings are absolutely infectious. Thanks to both, 20 years from now, when we think of summer 2012, "Call Me Maybe" will still come to mind.
