> Oldies is a term commonly used to describe a radio format that concentrates on a period 15 to 55 years before the present day… In the early 2000s, 1970s music was increasingly included, and 1980s music is beginning to also be called “oldies”, though the term “classic hits” is used to distinguish the new oldies from the Baby Boomer oldies.
