Bieber also notches his own personal best sales week, beating the 291,000 that "My World 2.0" sold in its second week back in April of 2010.
Justin Bieber's Next Single: 'As Long As You Love Me'
Click here to check out a full recap of the week's top 10 selling albums and digital songs.
Last Wednesday (June 20), industry sources had initially projected that "Believe" was going to debut with between 410,000 to 440,000. That figure was scaled back to 390,000 to 410,000 by Friday (22) and then down to 360,000 to 380,000 by Sunday (24). As we've noted previously, estimating future sales is difficult and projections can change on a daily basis. "Believe's" original forecast was inflated by the set's huge first-day sales and significant number of pre-orders.
Bieber previously led the Billboard 200 with "My World 2.0," 2011's "Never Say Never: The Remixes" and "Under the Mistletoe." "Believe" is his sixth top 10 effort overall -- he's only missed the No. 1 rung with his "My World" debut (No. 5) and "My Worlds Acoustic" (No. 7).

"Believe" was led by the hit single "Boyfriend," which debuted and peaked at No. 2 on the Billboard Hot 100. The set's second official single is "As Long As You Love Me," and its radio promotion will begin in earnest on July 9.
During release week, Bieber was in full-on promotion mode to tout the new album. NBC aired a two-night special dedicated to the star on June 20-21, while he sat down for a live YouTube chat with NBC personality Jimmy Fallon on June 21. He also stopped by MTV on June 19 for a "TRL"-style "Bieber Live" show and visited CBS' "Late Show With David Letterman," BET's "106 & Park" and ABC's "The View" (all on June 20).
