If Justin Bieber's "Believe Acoustic" reaches No. 1 on the Billboard 200, it will mark two historic achievements for the singer/songwriter.
First, he'll be the only artist in history to have five No. 1 albums before turning 19. Presently, both he and Miley Cyrus are tied with four chart-toppers at such a young age. Cyrus, now 20, logged her so-far quartet of No. 1s between 2006 and 2009. Her last No. 1-the Hannah Montana: The Movie soundtrack-hit the top of the chart dated May 2, 2009, when she was 16 years and five months old.

Second, Bieber may become just the 10th act to score a No. 1 album in four consecutive years.
In 2010, he topped the list with My World 2.0 and followed that in 2011 with Never Say Never: The Remixes (EP) and Under the Mistletoe. Last year, he debuted at No. 1 with Believe.
Jay-Z has the longest streak of consecutive years with No. 1 albums-seven. Between 1998 and 2004, he tallied at least one chart-topper. In 2004, he doubled up, scoring leaders with both Unfinished Business (with R. Kelly) and MTV Ultimate Mash-Ups Presents: Collision Course (with Linkin Park).
Aside from Jay-Z, the other acts with No. 1 albums in four (or more) years in a row are: the Beatles (six years, 1965-70) Paul McCartney/Wings (five, 1973-77), Herb Alpert & the Tijuana Brass (four, 1965-68), Garth Brooks (four, 1991-94), Chicago (four, 1972-75), Elton John (four, 1972-75), the Rolling Stones (four, 1971-74) and Cyrus (four, 2006-09).
Bieber graces the cover of this week's Billboard magazine in what is the lone major interview he's done for the new album. Buy the issue here  -- also on the iPad  -- and return to Billboard.com on Monday to read the exclusive cover story and get a first listen of a track from the record.
