omg Jump is AMAZING. i think it's their best song from the year, right next to Infinity. the PV was their best PV ever, IMO! the train in the PV is the same train i take to school everyday

(well, it's not the exact same train, since i live in a different part of NY. but that's what the trains look like

) and the cell phone that one of the ladies was holding (i think it's called a blackberry, i forgot) is the same exact phone as my friend's.
ANYWAY, chisa looked stunning and i loved how they showed her in those screens in times square at the end. awesome PV overall!
