Martina McBride threw out the rule book in choosing songs for her upcoming 'Eleven' album. On Wednesday night, she shared three of her favorite songs from the project -- in stores on October 11 -- during 'CMT Unplugged: Martina McBride.' The online special also featured McBride covering 'Love Song' by Sara Bareilles.

Among the new songs she played and discussed is her current single, 'Gonna Love You Through It.' It's one of the more serious songs on an otherwise fun album. McBride said she was struck by not only the story of a woman with three kids battling breast cancer, but by how supportive the woman's husband was. "It just says a lot of things that I've never heard sung before in a song," she says in the video. "It's just really powerful."

Another new song, 'Always Be This Way,' was co-written by McBride and songwriters Hillary Lindsey and Brett James. The trio wanted to write a fun love song, and someone threw out a lyric with the word "stupid" in it. "I said, 'Let's do it. Why can't we put stupid in a song? I love the word stupid,'" McBride says. Lindsey jokingly suggested the 'Boom, boom, boom' lyric, and it stuck.

The third new track that McBride performs, 'Watcha Gonna Do,' is a slow, soulful ballad. "I think it's one of my favorite things I've ever recorded. I just really love it," McBride says. The song is about a woman asking her man to start treating her right to avoid her leaving. It's a powerful, last-ditch effort to save a failing relationship.

A clip of McBride singing her 1995 hit 'Safe in the Arms of Love' is also available at CMT. 'Eleven' is McBride's first album since leaving RCA for Universal Republic. The album also features her Top 20 hit 'Teenage Daughters.'
