Mountains was the band's final album for BNA.
Released in late 2006, it was produced by Mark Bright, whose other production credits include Blackhawk, Rascal Flatts, and Carrie Underwood.
Its title track, co-written by Larry Boone, went to number 10 on the country charts, while followup "Nothing to Prove" peaked at 51.
Erlewine criticized the band for taking "fewer risks than ever" on the album.
Billboard writer Ken Tucker praised the album for containing positive messages in the singles, while also noting the use of vocal harmony and country-rock instrumentation.
Jeff Lincoln of Country Standard Time criticized some of the songs for overly "sensitive" lyrics, but felt that "Always in the Band", a song about a singer attempting to balance his career and family life, was "personal".

In March 2007, Lonestar was dropped from BNA's roster due to declining sales.
Guitarist Michael Britt attributes the group's commercial downfall in the mid-2000s to the label's choices in singles, saying in an interview with CMT, "I think we painted ourselves into a corner... They started putting out a bunch of family-type songs.
I think that really pigeonholed us.
The majority of the band didn't really want to continue doing that same thing.
But that's what kept getting put out."
McDonald also announced that he would be leaving the group at the end of 2007 to begin a solo career.
Cody Collins, who had previously been the lead singer of the band McAlyster in 2000, was confirmed as his replacement.
Lonestar's first release with Collins as lead singer was the 2007 Christmas music compilation titled My Christmas List, available exclusively at the restaurant and gift shop chain Cracker Barrel.
Dan MacIntosh of Country Standard Time reviewed this album favorably, calling Collins' voice a "comfortable fit" while also praising the variety of arrangements given to traditional Christmas carols on the album.

McDonald also released a Christmas album in late 2007, titled If Every Day Could Be Christmas.
It was followed a year later by I Turn to You, a contemporary Christian music album released via Stroudavarious Records (later known as R&J Records).
After this album, he had two chart singles in 2009, both peaking at number 51: "How Do I Just Stop" and "Six Foot Teddy Bear".
The former appeared on his third solo album, Slow Down, which was released via Loremoma  in 2010.

The group's first single to feature Collins on lead vocals was "Let Me Love You", which was released in early 2008 on Saguaro Road Records.
It is the first single from the album Party Heard Around the World, released on April 27, 2010 and produced by the band itself.
A review in Country Standard Time criticized Collins' vocals as being too similar to those of Keith Urban, while also saying that it had "[a] lot of songs about love, life and relationships.
The usual clichés you find in today's pop-country."
Erlewine found little difference in the band's sound following the change to Collins, saying that "they’re still gunning for a wide audience because commercialism simply is in their bones.
The Lonestar name means nothing if the band isn't big, slick, and crowd-pleasing."
