Kenny Chesney, Barbra Streisand and Tony Bennett & Lady Gaga are battling for No. 1

Two days ago, on Sept. 24, it seemed like Kenny Chesney's new The Big Revival album was likely heading for No. 1 on next week's Billboard 200 chart. But now, he's in a dead heat with Barbra Streisand's current No. 1 champ, Partners. And not too far behind both of them: Tony Bennett and Lady Gaga with their duets album, Cheek to Cheek.

Barbra Streisand Makes History at No. 1 on Billboard 200

Industry forecasters suggest Chesney and Streisand's new albums may sell around 125,000 each in the week ending Sept. 28, while Bennett and Gaga are aiming for 120,000. Any one of the three albums may come out on top.

The Billboard 200's new top 10 will be revealed on Wednesday, Oct. 1.

Also aiming for debuts in the top 10: alt-J's This Is All Yours (with around 60,000), Pentatonix's PTX, Vol. III (45,000) and possibly Joe Bonamassa's Different Shades of Blue (25,000). A wild card in the mix is Thom Yorke's new surprise album, Tomorrow's Modern Boxes, which was released on Sept. 26. It's too early to tell if sales of the album will be reported to Nielsen SoundScan, which compiles data that powers Billboard's sales charts.
