'Call Me Maybe' is Billboard's Song of the Summer.

Hey, we just met her, but this doesn't seem so crazy: After a season of pop culture ubiquity, Carly Rae Jepsen's "Call Me Maybe" tops Billboard's Songs of the Summer chart, presented by Pepsi. (The tally is based on cumulative performance on the Billboard Hot 100 from Memorial Day through Labor Day.)

The Canadian pop singer's maiden American hit spent nine weeks atop the Hot 100. After fellow Canadian Justin Bieber revealed his affinity for the song on Twitter, its popularity surged, spurring viral covers by everyone from the all-male Harvard baseball team to President Obama (thanks to digital ingenuity that prompted a mashup of its lyrics culled from his speeches).

Jepsen is the first artist to claim top Song of the Summer honors with a first Hot 100 entry since Katy Perry won the mantle in 2008 with "I Kissed a Girl." In the Songs of the Summer chart's 28-year archives, only two other women have earned the accolade with debut Hot 100 hits: Christina Aguilera ("Genie in a Bottle," 1999) and Mariah Carey ("Vision of Love," 1990).
