Justin Bieber Bound for Fifth No. 1 Album on Billboard 200 Chart

Unless something highly unexpected happens, Justin Bieber will collect his fifth No. 1 album on the Billboard 200 chart next week with "Believe Acoustic." Industry sources say that the set could sell between 180,000 to 190,000 copies by the end of the tracking week on Sunday, Feb. 3.

"Believe Acoustic" might be the only album to sell in excess of 100,000 this week. The next biggest set looks to be Andrea Bocelli's new Passione, which may move around 85,000.

Should "Believe Acoustic" debut at No. 1, it will follow Bieber's earlier chart-toppers "My World 2.0" (2010), "Never Say Never: The Remixes," "Under the Mistletoe" (both in 2011) and last year's "Believe."

The new album may also give Bieber a No. 1 album in four consecutive years -- something only nine earlier acts have done in the nearly 57-year history of the Billboard 200 chart.

Sources indicate that "Believe Acoustic"'s digital sales will be particularly robust, with upwards of 70% of its debut coming from downloads. Digital pre-orders of the set were strong as well -- they may equate to 35% of the set's digital sales debut.

Other albums set for top 10 bows next week include Tegan & Sara's "Heartthrob" and Local Natives' "Hummingbird."
