It's one of the finest pop albums of the year so far and now it's the No. 1 in the country.

Sia's latest full-length, 1000 Forms of Fear, has earned the singer-songwriter her first No. 1 album with 52,000 copies sold during its first week, according to Nielsen SoundScan.

While this may be her first solo reign atop the Billboard charts, she's had plenty of top 10 hits, having been featured on David Guetta's "Titanium" and Flo Rida's "Wild Ones," in addition to writing Rihanna's No. 1 "Diamonds," Beyonce's "Pretty Hurts" and many more.
