Carrie Underwood better make some more room in her trophy case. The singer's compilation album, Greatest Hits: Decade #1, has been RIAA certified platinum. This marks the first country record since its own December 2014 debut to sell over one million units. 

During the project's first week of release, it premiered at the top of Billboard’s Top Country Albums chart with sales of 94,000 copies. This marked the biggest debut of any female artist since 2005, when Underwood herself set the record with Some Hearts.

Greatest Hits is a 25-song collection reminiscing about the first 10 years of the superstar's career, also producing two new singles in "Something in the Water" and "Little Toy Guns." Both songs have earned recognition from the Grammys while also finding their ways to the top of the country airplay charts. Both singles have also earned RIAA certifications in their own right, with "Little Toy Guns" earning gold status and "Something in the Water" being certified platinum.

A lot has changed since the Greatest Hits: Decade #1 debuted, including the release of a new (fully new) album and the announcement of a tour. There was also that whole becoming a mom thing.

Storyteller was released this past October and has already produced one No. 1 single, "Smoke Break," with another one, "Heartbeat," quickly climbing up the charts. The tour to support the album, the Storyteller Tour - Stories in the Roundis slated to kick off on Jan. 30 in Jacksonville, Fla.
