Diamond Rio and their longtime record label, Arista Nashvile, have parted ways amicably, according to Billboard magazine. The band released their debut single, "Meet in the Middle," on the label in 1991, marking the first of five No. 1 hits and 19 Top 10 hits. Released in May, the band's Greatest Hits Vol. II includes "One More Day," "Beautiful Mess" and "I Believe." The project followed three platinum and five gold albums for the label.
