Timeless was a 24-hour satellite music service of Citadel Media (through Citadel Broadcasting). It has distributed a mix of soft oldies and adult standards to radio stations around the United States. It was a combination of two former formats: gold-based adult contemporary Unforgettable Favorites (also known as "Memories") and adult standards Timeless Classics/Timeless Favorites (originally known as "Stardust"). Since 2007, it was simply known as "Timeless", still using the "Timeless Favorites" branding sparingly.
