Bruno Mars’ “Locked Out Of Heaven” remained locked into the top spot on the Billboard Hot 100 for the fifth week.

The tally makes “Locked” Mars’ longest stint at No 1, surpassing the four weeks that both “Just The Way You Are” and “Grenade” spent at the top, according to Billboard.

Last week, “Locked” looked like it would be fending off a charge at the top spot from Taylor Swift’s “I Knew You Were Trouble.” Instead, Swift’s song drops 2-3, swapping places with Rihanna’s Diamonds, which rises 3-2.  The Lumineers’ “Ho Hey” stays at No. 4.

The star of the week is Macklemore & Lewis’s “Thrift Shop,” which leaps 10-5. While the rap song is gaining at radio, its high chart position has been propelling largely by digital sales and streaming.

American Idol” winner Phillip Phillips’ “Home” continues to have a healthy life, rising 6-9 in its 28th week on the chart. Justin Bieber’s “Beauty and a Beat,” featuring Nicki Minaj, falls 5-7.

After loitering in the top 15 for five weeks, Will.i.am’s “Scream & Shout,” featuring Britney Spears, breaks into the Top 10, yelling its way 12-8. The tune marks Will.i.am’s first Top 10 as a lead solo artist.

Maroon 5’s “One More Night” slides 8-9, while Flo Rida’s “I Cry” rises 11-10.
