The Grand Ole Opry is marking its 100th anniversary with the release of a special double album, Opry 100: Country's Greatest Songs. The collection features 20 legendary country tracks selected from a curated list of the 100 best songs of all time. This milestone project will be available in physical CD format and is scheduled for release on Nov. 7. The 100 most renowned country songs list was formed through a combination of six lists, representing each decade, that include songs spanning the 1930s to the present day, and thus represents nearly 100 years of song legacy. The lists are based upon decades; 1930s-60s, 1970s, 1980s, 1990s, 2000s-2010s, and the decade of the present day.
