The phrase for rock from the 60s and 70s that this generations' dads listened to because they didn't now any better. The term is used by people who consider themselves cultured and varied, and refuse to believe that it's possible that people actually could like classic rock.

Music that Boomers would listen to and/or write themselves. Picturing a 35-50 year old dance to these tracks puts your stomach in a knot. Inherently uncool. However, some very good bands today write embarrasing Dad Rock tracks.

They also tend to have long titles.
