Lonestar’s “I’m Already There” stays at No. 1 for a fifth consecutive week on the Billboard Hot Country Singles & Tracks chart, but the group’s album of the same name drops to No. 2 after debuting at No. 1, displaced by the O Brother, Where Art Thou? soundtrack.

The singles chart competition heats up this week, with Montgomery Gentry’s “She Couldn’t Change Me” climbing to No. 2, Jamie O’Neal’s “When I Think About Angels” rising to No. 3 and Brad Paisley’s “Two People Fell in Love” jumping from No. 7 to No. 4.

Brooks & Dunn’s “Only in America” captures “Airpower” honors, registering at No. 20 in its fifth week on the chart. Tim Rushlow’s “Crazy Life” is the “Hot Shot Debut” at No. 56. Also hitting the singles chart is a downloaded version of “America the Beautiful” featuring Toby Keith, Vince Gill and other country stars. The track was used in an ABC News special and has not been released as a single or album track.

In its 12th non-consecutive week at No. 2, the O Brother, Where Art Thou? soundtrack also is this week’s “Greatest Gainer,” showing the largest increase in unit sales. There were no debuts on the Top Country Albums chart, but bluegrass favorite Rhonda Vincent’s The Storm Still Rages, at No. 59 in its second week, earns “Pacesetter” status with the largest percentage sales growth.
