Billie Eilish’s "Happier Than Ever" music album that debuted on July 30 continues to stay at the top for the second week on Billboard 200 albums chart.

The album has earned 85,000 equivalent album units in the U.S. by end of Aug. 12, marking a 64% decline compared to the first week.

"Happier Than Ever" became the second album of 2021 to hold the No. 1 spot for two consecutive weeks after Morgan Wallen’s "Dangerous: The Double Album." Wallen's album debuted on Jan. 23 and stayed at No. 1 for 10 weeks.

Before Eilish, it was Olivia Rodrigo's "Sour," which ranked No. 1 but has been moved to the No. 2 spot with 61,000 equivalent album units.

The Billboard 200 chart calculates the equivalent album units based on multi-metric consumption including streaming equivalent albums (SEA), track equivalent albums (TEA) and Units comprise album sales.

Each unit equals one of these activities -- 10 individual tracks sold from an album, one entire album being sold, 1,250 paid/subscription or 3,750 ad-supported.

Last month, the 19-year-old singer opened up about her music album on Instagram and noted that "this is my favorite thing I've ever created and I am so excited and nervous and EAGER for you to hear it. I can't even tell you. I've never felt so much love for a project than I do for this one. Hope you feel what I feel."

Prior to her album release, the singer also revealed what her fans would take away from the album.

"The main thing that I would hope is, for people to hear what I say, and then go, ‘Oh, God, I feel like that I didn’t know that I felt like that," Eilish told Vevo in July. "But this is how I feel,’ and maybe make a change in their life that makes them happier," the singer added.

On the work front, Eilish is currently filming a new documentary, "What Do You Want from Me?" which is slated to release next year. The documentary will revolve around the singer's journey in the music industry and her personal life.
