Problem: Background: Rascal Flatts is an American country band formed in Columbus, Ohio in 1999. It is composed of Gary LeVox, his second cousin Jay DeMarcus and Joe Don Rooney. DeMarcus is also a brother-in-law of country music singer James Otto, and formerly one-half of the Christian music duo East to West. They are best known for performing a cover of Tom Cochrane's "Life Is a Highway".
Context: Rascal Flatts released their first greatest hits CD, Greatest Hits Volume 1, on October 28, 2008. The album contains 13 of their biggest songs, starting with "Prayin' for Daylight" and going through "Life Is a Highway". The limited edition of the album contains a second disc with three Christmas songs: "White Christmas", "Jingle Bell Rock", and "I'll Be Home for Christmas". A year later in October 2009, they released a second edition of their greatest hits collection, this time with a second disc containing live performances of "Take Me There", "Summer Nights", "Me & My Gang", and "Winner at a Losing Game".  Rascal Flatts released the first single, "Here Comes Goodbye", from their album Unstoppable to radio on January 20, 2009, and the album was released on April 7. "Here Comes Goodbye" became the group's tenth No. 1 hit. The song was co-written by American Idol season six finalist Chris Sligh. The second single, "Summer Nights", co-written by Gary LeVox, was released in early May 2009, debuted at No. 57 and topped out at No. 2 on the country charts. The group performed "Summer Nights" at the CMT Music Awards, Oprah's Kickoff Party, and the finale of America's Got Talent. The third single off the album, "Why", peaked at No. 18 on the country charts. Rascal Flatts performed "Why" on The Tonight Show with Conan O'Brien.

Problem: Background: Deborah Anne "Debby" Boone (born September 22, 1956), is an American singer, author, and actress. She is best known for her 1977 hit, "You Light Up My Life", which spent ten weeks at No. 1 on the Billboard Hot 100 chart and led to her winning the Grammy Award for Best New Artist the following year. Boone later focused her music career on country music resulting in the 1980 No. 1 country hit "Are You on the Road to Lovin' Me Again". In the 1980s, she recorded Christian music which garnered her four top 10 Contemporary Christian albums as well as two more Grammys.
Context: With her older sisters married and younger sister Laury in college, Boone was actively encouraged by producer Mike Curb to launch a solo career. Boone released her first solo effort, "You Light Up My Life" (which had been featured in the film of the same name) in 1977. The song became the biggest hit of the 1970s spending ten consecutive weeks at No. 1 on the Billboard Hot 100 -- longer than any other song in Hot 100 history to that point. (In 2008, Billboard ranked the song No. 7 among all songs that charted in the 50-year history of the Hot 100.) The song earned Boone a Grammy Award for Best New Artist and an American Music Award for Favorite Pop Single of 1977. She also received Grammy nominations for Best Pop Vocal Performance - Female and Record of the Year won by, respectively, Barbra Streisand ("Love Theme From "A Star Is Born" (Evergreen)") and the Eagles ("Hotel California"). "You Light Up My Life" also succeeded on Billboard's Adult Contemporary (No. 1 for one week) and Country (No. 4) singles charts. The single and the album (No. 6 Pop, No. 6 Country) of the same name were both certified platinum.  The song, written and produced by Joe Brooks, was from the film of the same name. Brooks earned Song of the Year awards at both the 1978 Grammys and Oscars for writing the song. (Boone performed the song at both awards shows.) Boone's version was not used in the movie or featured on its soundtrack. The song was lip-synched in the film by its star, Didi Conn, performing to vocals recorded by Kacey Cisyk. It was written as a love song, but Boone interpreted the song as inspirational and stated that she recorded the song for God.  Boone's overnight success led to a tour with her father and frequent television appearances, but she was unable to maintain her success in pop music after "You Light Up My Life". Her follow-up single, "California" (also written and produced by Joe Brooks), peaked at No. 50 Pop and No. 20 AC. "California" was included on Boone's second album, Midstream, which faltered at No. 147 Pop. Her next single, the double-sided "God Knows"/"Baby I'm Yours", also struggled, peaking at No. 74 Pop, becoming her last entry on the Hot 100. However, the single charted AC (No. 14) and returned Boone to the country chart (No. 22). Boone then released another movie theme, "When You're Loved", from The Magic of Lassie. Like "You Light Up My Life", the song was nominated for an Academy Award for its composers, the Sherman Brothers, but it failed to replicate the success of her first single charting only No. 48 AC. Boone's wholesome persona contrasted with the image-conscious pop-music industry, leading her career in different musical directions.
Question: what was her greatest accomplishment?
Answer:
a Grammy Award for Best New Artist and an American Music Award for Favorite Pop Single of 1977.
