easy

Easy listening (including mood music) is a popular music genre and radio format that was most popular during the 1950s to 1970s. It is related to middle-of-the-road (MOR) music and encompasses instrumental recordings of standards, hit songs, non-rock vocals and instrumental covers of selected popular rock songs. It mostly concentrates on music that pre-dates the rock and roll era, characteristically on music from the 1940s and 1950s. It was differentiated from the mostly instrumental beautiful music format by its variety of styles, including a percentage of vocals, arrangements and tempos to fit various parts of the broadcast day.
Easy listening music is often confused with lounge music, but while it was popular in some of the same venues it was meant to be listened to for enjoyment rather than as background sound.
