Look for lots of action on the album chart  that comes out Wednesday as  Rob Thomas and Brad Paisley are among the two artists vying for the top spot, but it appears  "Now 31," the never-ending series of the latest top hits will beat the pop singer and the guitarslinger.

"Now 31," which includes recent chart toppers from the likes of the Black Eyed Peas and Britney Spears, will sell around 140,000 copies, according to Hits Daily Double.

HDD then has  Michael Jackson's "Thriller" at No. 2, dropping from No. 1 after last week's resurgence of Jackson titles following his death. HDD's chart differs from Billboard's Top 200 in that Billboard doesn't allow catalog titles back on the Billboard 200.

As of July 4, Hits gives Paisley 's "American Saturday Night" a slight nod over Thomas's "Cradlesong," and we think that's probably about right.  Paisley has already scored a No. 1 off of the new album with the strong "Then," while Thomas's first single "Her Diamonds" is still climbing.  Both had strong set ups and should sell steadily over a long period of time.

"Now," Paisley and Thomas are joined by Wilco, Killswitch Engage and Jeremih among the other debuts in the top 10 alone. That's quite a great range of musical genres in the upper regions, but it says a lot about the current state of the music industry  and Jackson's enduring musical legacy (plus our obsession with Jackson's death) that he beats them all.
