Colbie Caillat’s “Breakthrough” Leads Skillet, Imogen Heap, Arctic Monkeys, Jet (Album Sales)

Colbie Caillat, the MySpace sensation who hit the big time with debut album singles “Bubbly” and “Realize,” will win next week’s album sales chart, according to tracking by Hits Daily Double

Her sophomore album “Breakthrough,” presently the sales leader on iTunes, is tracking to move 95-100,000 units this week. Caillat’s debut “Coco” peaked at five en route to its double platinum sales finish. The album kicked off with “Fallin’ For You,” a track that has yet to really pop for the singer/songwriter.

Following Caillat (among new releases) is Skillet’s “Awake,” which is looking good for a total in excess of 55,000. A surprise hit with the iTunes audience–similar to last week’s Third Eye Blind release–the album should top Imogen Heap’s “Ellipse” (on track for 45-50,000).

“Now Country 2” should land in the 35-45,000 range. Tracking for other debuts includes LeToya’s “Lady Love” (25-30,000), Arctic Monkeys’ “Humbug” (25-30,000), Ingrid Michaelson’s “Everybody” (20-25,000), Collective Soul’s self-titled release (18-22,000), Matisyahu’s “Light” (15-18,000), Love & Theft’s “World Wide Open” (15-18,000), Jet’s “Shaka Rock” (15-18,000), Queen Latifah’s “Persona” (15-18,000), Needtobreathe’s “The Outsiders” (12-15,000) and David Guetta’s “One Love” (10-12,000).
