After nine weeks of climbing, Meghan Trainor’s breakout single “All About That Bass” has finally reached the top spot on the Hot 100, moving up from No. 2 last week. It’s a big deal for a promising young artist and one of the more charming contenders for Song of Summer title, but the bigger news might be who she beat for the position: Taylor Swift, whose “Shake It Off” slips to No. 2 after just two weeks at No. 1.
“Shake” easily debuted there thanks to a half million in sales and 50 million YouTube plays in its first week out, but its reign atop the chart was almost noticeably brief compared to other recent number ones. Magic!’s “Rude” spent six straight weeks there before “Shake” knocked it out, and Iggy Azalea and Charli XCX’s “Fancy” spent seven. Swift’s sworn enemy Katy Perry spent four weeks at No. 1 at the beginning of the year with “Dark Horse,” while Pharrell’s colossal “Happy” held the position for an impressive 10 weeks. Even John Legend’s milquetoast “All of Me” held the spot for a week longer than “Shake.”
