There's no denying that there's been an awful lot of pent-up demand for new music from Van Halen -- and that longtime fans of the band should turn out in droves to pick up 'A Different Kind of Truth,' its long-awaited new album with original lead singer with David Lee Roth. But could it actually debut on top of the Billboard album charts?

According to tracking data, 'Truth' looks set to debut with first-week sales between 180,000 and 200,000 copies -- below the 233,000 they moved the last time they released new Roth recordings, with 'Best of Volume 1' in 1996, but still pretty impressive in the current sales climate.

It might not be enough, however, to dislodge Adele's hugely successful '21' from the top spot. Industry sources speculate that a Grammy sales bump could benefit Adele, who's favored to win multiple awards, and push '21' to its 20th non-consecutive week at No. 1.

A chart-topping release would likely be especially sweet for Roth, who's never had a No. 1 studio album with Van Halen; all four times the band has done it, they did it with Sammy Hagar, who replaced Roth in 1985 and led the band through a commercially successful decade before departing in '96.
