Taylor Swift loves to remind everyone that she listens to all the new, up-and-coming music. And because she seems to consider herself something of a kingmaker, she also enjoys bringing them out onstage with her or inviting them to hang out and possibly collaborate (Tegan and Sara, Lorde, Ed Sheeran, etc.)
She did it again over the weekend during her show at London's O2 Arena, when she bragged about hearing British music six months before it hits the U.S., subsequently bringing out Sam Smith to perform his single "Money on My Mind" with her.
Of course, "Money" has been available in the States for two months now, as you're probably aware.
Disregard Swift's intro on the fan footage below and watch the pair perform the song in front of an enthusiastic crowd.
