Lorde’s “Royals” logs its fourth week atop the Billboard Hot 100, giving the New Zealand singer the longest reign by a female artist in the top spot this year.  We have to go back to last summer when Carly Rae Jepsen’s “Call Me Maybe”  ruled at No. 1. for nine weeks to find a longer stint by a female.

Katy Perry, whose new album, “Prism,” came out Tuesday (23), claims two spots on the Hot 100- her former No. 1, “Roar,” is at No. 2, while new single “Unconditionally” bows at No. 54.

“Roar” switches places with Miley Cyrus’s “Wrecking Ball,” which drops to No. 3.

Avicii’s “Wake Me Up!” remains at No. 4, while Drake’s “Hold On, We’re Going Home” (featuring Majid Jordan)” holds at No. 5, according to Billboard.

Ylvis’s “The Fox”  stays at No. 6, while Eminem’s new single, “Rap God” bows on the chart at No. 7, the only new entry into the Top 10.

Otherwise, Jay Z’s “Holy Grail” (featuring Justin Timberlake) slides 7-8, Lady Gaga’s “Applause” drops 8-9 and Robin Thicke’s “Blurred Lines”  slips 9-10 in its 21st week in the Top 10.
