Billboard announced on Thursday that Iggy Azalea's hit single "Fancy" was their Song of the Summer.

The track, which featured Charli XCX, hit the top of the summer chart and then just never looked back, with no other single able to dethrone it, even for a week, Billboard reports. The Songs of the Summer chart runs from Memorial Day through Labor Day.

The song, which also appeared in the Hot 100's top five for six weeks during the summer, is the first to do so since 2010 when Katy Perry's "California Gurls" ruled the chart.

While Billboard crowned "Fancy," Spotify called Calvin Harris' "Summer" their top pick, according to USA Today reports. The track was their most streamed song of the summer.

The other popular tracks that appear in the top five of Spotify's list include Ariana Grande's "Problem," Magic!'s "Rude," Azalea's "Fancy" and Jason Derulo's "Wiggle."

Azalea's major label debut The New Classic will soon be re-released and she took to Twitter to let fans know a little about it. "Shooting the album re pack covert art this week. can't wait for you guys to hear some new stuff. six new tracks."

She also tweeted, "me and ellie goulding have a nice little numberrrr together on there too. FYI."
