Brad Paisley's career is still in overdrive as 5th Gear debuts at No. 1 this week on the Billboard country albums chart. He's also parked at No. 3 on the all-genre Billboard 200, behind two other big debuts -- Bon Jovi's Lost Highway and the White Stripes' Icky Thump. (Although Bon Jovi's new album is inspired by Nashville, it is not considered a country album on the Billboard chart.)

Paisley knocks Toby Keith's Big Dog Daddy to No. 2. Taylor Swift rises to No. 3, followed by the latest albums by Big & Rich, Carrie Underwood, Jason Aldean, Tim McGraw, Rascal Flatts, Sugarland and Alison Krauss, at No. 4 to No. 10, respectively. Paisley's previous album, Time Well Wasted, continues to sell well, appearing at No. 18. No other new albums debuted this week.

On the country airplay chart, Montgomery Gentry notches another No. 1 hit, "Lucky Man." (The corresponding album, Some People Change, is at No. 31.) It's the third No. 1 single for the duo, joining "If You Ever Stop Loving Me" and "Something to Be Proud Of." Montgomery Gentry's luck may not last because George Strait's "Wrapped" (at No. 2) and Big & Rich's "Lost in This Moment" (at No. 3) continue to gain airplay.

Three previous No. 1 singles come in next -- Tracy Lawrence's "Find Out Who Your Friends Are," Paisley's "Ticks" and Emerson Drive's "Moments," in fourth through sixth place, respectively. Keith Urban's "I Told You So," Jake Owen's "Startin' With Me" and Kenny Chesney's "Never Wanted Nothing More" hold onto their positions at No. 7 and No. 9, respectively. Billy Currington's recent No. 1, "Good Directions," falls to No. 10.

At No. 52, Paisley's "Online" earns the week's highest debut on the country singles list. Other new entries include Lyric Street artist Lisa Shaffer's "Just One" at No. 55, Clint Black's "The Strong One" at No. 56, Blake Shelton's "The More I Drink" at No. 57 and Crossin Dixon's "Guitar Slinger" at No. 58.

On the bluegrass album chart, Cherryholmes II: Black and White retains its No. 1 position in its second week. Krauss' latest compilation isn't listed on the bluegrass chart but her Union Station bandmate Ron Block debuts at No. 7 with Doorway.
