Given the question: What number did the album released on September 5, 2006 debut at on the Billboard 200?  Answer the above question based on the context below:  In December 2005, Audioslave received its third Grammy nomination at the 48th Grammy Awards in the Best Hard Rock Performance category for "Doesn't Remind Me." Audioslave began recording their next album; Cornell had already expressed his desire to make "an album every year or year-and-a-half" even before Out of Exile was released. In early July 2005, after the conclusion of the European tour, the band returned to the studio to write new songs; Morello said their aim was to "blur the lines between rehearsing, recording and touring." The actual recording began in January 2006, with plans to release the album, Revelations, in June. This time, the band chose Out of Exile's mixer, Brendan O'Brien, as producer. Audioslave had 20 songs written and recorded, 16 of those in only three weeks. The album's release date, however, was postponed to early September, and the band cancelled their previously announced European tour, to have a new album to support, when they embarked on touring.

Cornell immediately denied the rumors, stating "We hear rumors that Audioslave is breaking up all the time. ... I always just ignore [them]." In the same interview, he also discussed his intentions to record a new solo album, the second in seven years, before the end of August. A special marketing campaign preceded the new album's release in August, when the art concept was featured on Google Earth as a fictional utopian island, Audioslave Nation, created in the South Pacific. Several songs from the upcoming album appeared on movie and video game soundtracks; "Wide Awake" and "Shape of Things to Come" were featured in Miami Vice, while "Revelations" was on the soundtrack of Madden NFL 07. Revelations was released on September 5,...
