TAG, THEY'RE IT

K-Pop troupe 2NE1 is once again the week's biggest jumper, thanks to a ubiquitous Microsoft ad. The duet of Rhiannon Giddens (a new obsession in our office) and Iron & Wine on Parenthood also made big ripples, as did reggae star Sister Nancy's tune in The Interview. But the jump that disrupts the top of the rankings is the Rihanna-Kanye-Sir Paul sensation, which soars to #2 just as the threesome's Grammy performance is announced.

Among the noteworthy jumpers outside the Top 5 is the new one from Nick Jonas, "Chains," which moves up 27 places.

In the U.K., Rihanna and company soar a stunning 178 places to #6. You'll find the British chart here; for future refererence, you'll always find Shazam data under "The Vibe" tab in our top black menu bar.
