Tourmates Keith Urban and Kenny Chesney dominate the Billboard country charts again this week, with John Michael Montgomery and Montgomery Gentry also making strong showings.

After three weeks in second place, Urban finally tops the Billboard country singles chart with "You'll Think of Me." It's the third No. 1 from Golden Road, which holds steady at No. 2 on the country albums chart. Meanwhile, Chesney's When the Sun Goes Down remains at No. 1 on the albums chart, and the Uncle Kracker duet of the same name falls a notch to No. 2 on the singles chart.

Montgomery's Letters From Home debuts at No. 3 on the albums chart, followed by the latest projects from Toby Keith, Tracy Lawrence, Alan Jackson, Josh Turner, Rascal Flatts, Brooks & Dunn and Shania Twain. Following a lively performance on the CMT 2004 Flame Worthy Video Music Awards, Montgomery Gentry leap seven spots to No. 30 with their platinum My Town. Their new album, You Do Your Thing, arrives May 18.

No songs enter the Top 10 for the first time this week, although Rascal Flatts' "Mayberry," Montgomery's "Letters From Home," Gretchen Wilson's "Redneck Woman," Lawrence's "Paint Me a Birmingham" and George Strait's "Desperately" continue to ascend the chart, landing at Nos. 3 to 7, respectively. Buddy Jewell's "Sweet Southern Comfort" falls to No. 8, as Lonestar's "Let's Be Us Again" and Montgomery Gentry's "If You Ever Stop Loving Me" remain at Nos. 9 and 10.

Clay Walker's comeback continues to take shape. With "I Can't Sleep" getting a significant boost in radio airplay, the single jumps two spots to No. 17. His album, A Few Questions, is at No. 30, up 12 spots from just two weeks ago. Farther down, independent artist Raymond Harris debuts Hurt by the Best at No. 50. It can't hurt that by purchasing a copy of the album at his record label's Web site, you also receive a raffle ticket for a free Harley-Davidson Sportster.

New singles charting this week include Sara Evans' "Suds in the Bucket" at No. 49, Jessi Alexander's "Honeysuckle Sweet" at No. 52, Travis Tritt's "The Girl's Gone Wild" at No. 54 and Patty Loveless' "I Wanna Believe" at No. 60.

On the Billboard 200, which tracks all album sales, Patty Griffin's Impossible Dream debuts at No. 67. In addition, two new albums appear on the bluegrass sales chart: Bluegrass Number 1's : A Collection of Chart Topping Songs at No. 4 and the Del McCoury repackaging High Lonesome and Blue at No. 11.
