Daughtry is quickly becoming one of the most popular live acts in rock, and the band members also happen to be huge baseball fans. Putting the two passions together, it was a no-brainer to have them in the MLB.com studios recently to perform.

Hot on the heels of their platinum-selling, self-titled debut album, Daughtry has been packing concert halls all over the country with its brand of infectious, hard-rocking pop featuring the lead vocals of Chris Daughtry.

They brought that energy, enthusiasm and talent to MLB.com, where they kicked back and did acoustic versions of four hit songs -- "It's Not Over," "Breakdown," "All These Lives" and "Home" -- that we'll be breaking out on the site over the next four days.

"It's Not Over," the first single on Daughtry, went platinum in April, just as the baseball season was kicking into gear, and it's ranked in the Top 10 of best-selling digital songs in 2007. "It's Not Over" turned out to be an astute choice as the band's debut single, too. It garnered critical acclaim from Billboard magazine, which wrote that the song was "tight, focused and ready to rock your face off" and Entertainment Weekly called it "ridiculously catchy."

"Breakdown," with music and lyrics by Chris, is a slower ballad, a classic break-up song with some hope of reconciliation. "Well, it's not the time to break down," he sings. "It's not the time to break up this love/Keep it together now." Chris often plays this one alone with an acoustic guitar in a live setting, allowing his powerful voice to be heard more clearly than when he's rocking out with the band.

"All These Lives" shows the depth of Chris' writing, with the slowed-down song, also often performed solo and acoustic in concert, dealing with the horrifying subject of child abduction.

"Home," the second single off of Daughtry, gained quite a bit of fame by being the song played on the sixth season of "American Idol" when contestants were voted off, and it peaked at No. 5 on the Billboard Hot 100 chart. Chris actually wrote the song the day before he left his North Carolina home to embark on the "American Idol" journey that eventually made him a household name to music fans everywhere.
