South Korean pop sensation PSY still can't get past Maroon 5 to land a number one hit in the U.S.

The star has pledged he'll perform Gangnam Style topless "in a place where everyone can watch" if the dancefloor favourite hits the top of the U.S. pop charts, but it's beginning to look like he'll be keeping his shirt on for good after Maroon 5 notched up a fifth week at number one on Wednesday (17Oct12) with One More Night.

Psy has been stuck at two for four weeks.

Meanwhile, Taylor Swift's I Knew You Were Trouble debuts at three, two spots ahead of the country superstar's former number one We Are Never Ever Getting Back Together, which holds at five on the new chart.
