Tim McGraw's upcoming greatest hits collection will feature six tracks never previously released on any of his albums, including four brand new songs. Tim McGraw Reflected: Hits Vol. 2 will be anchored by a series of No. 1 hits, including "Not a Moment Too Soon," "The Cowboy in Me," "Real Good Man" and "Live Like You Were Dying." Earlier this week, McGraw delivered two of the new songs to country radio -- "I've Got Friends That Do" (which he co-wrote) and "When the Stars Go Blue" (written by Ryan Adams). The other new songs are titled "My Little Girl" and "Beautiful People." The album also includes two previously-released duets -- "Over and Over" (first released on Nelly's 2004 album, Suit) and "Like We Never Loved at All" (which debuted on wife Faith Hill's Fireflies). Tim McGraw Reflected: Hits Vol. 2, McGraw's 10th album, will be released March 28.
