Kenny Chesney has another Gold album to his credit with his "Greatest Hits, Volume 2." The singer's second best-of collection has surpassed the 500-thousand mark in sales. Speculating on the popularity of such compilations, Chesney notes, quote, "I guess we do greatest hits projects so people can have all the hits in one place. Because between the radio and the albums sold, I know the fans know these songs!"He adds that he's glad his "Greatest Hits, Volume 2" gave him a new outlet for "I'm Alive," his collaboration with Dave Matthews. Describing the song as "just magic," Chesney says his "Greatest Hits" sequel allowed "I'm Alive" to get some radio airplay.
