No, not waiting for your honey to come back home from Germany or sitting in rumble seats.
Listening to some songs from the 1970s, certain themes and phrases were very common, but now almost never seen in popular music today. For instance, "stealing away" - a staple of rock songs in the 1970s, but now something that makes most think "what the hell does 'stealing away' mean?" Rock songs about cars and driving are also now very rare, although rap has taken up the slack somewhat with Escalades, "20s" and "box Chevys" occasionally mentioned in songs, but cars are rarely the central theme. Suburban teenage rebellion in the 1970s has been replaced by emo suburban teenage angst today.
What other themes used to be common in music not so long ago, but are now rare or nonexistent?
