“Mr. Mr.” by K-Pop group Girls’ Generation (2014) charted at #3 on the Korea K-Pop Hot 100 and #4 Billboard World Digital Songs chart. AllMusic’s review states that the track mixes “a hip-hop beat and EDM-inspired buildups and drops.”
After being introduced to verses, choruses, a spare breakdown at 2:40, and a bridge at 3:02, we’re hit with a big half-step key change at 3:19, only to run smack into another monster upward half-step shift at 3:35.
