Lounge music can also specifically refer to a form of "hip" (not "hip-hop") generally easy listening music that was popular during the 50's and 60's, yet distinct from what was "pop rock" of that era. This is considered to be the golden age of lounge music. At this time, while pop rock music was more popular with younger folks, lounge music was more popular with older folks. Typically, teenagers of the time would listen to pop rock, while their older siblings or parents would listen to lounge. However, the phrase lounge does not appear in textual documentation of the period, such as Billboard magazine or long playing album covers.
