Taylor Swift has scored a second week at the top of the U.S. pop charts.

Her latest hit Shake It Off debuted at number one on the Billboard Hot 100 countdown last week (27Aug14) and Swift has fought off challenges from Meghan Trainor, Jessie J, Ariana Grande and Nicki Minaj to stay on top of the girl-powered top five.

Trainer's All About That Bass rises to two, changing places with Minaj's Anaconda, while the hip-hop superstar's Bang Bang collaboration with Ariana Grande and Jessie J crashes into the top five at four.

Sam Smith is the only guy in the top five - his Stay With Me drops to five on the new chart.
