The experts on musical taste formation say that our tastes are mostly formed during our 14-24 age range. For example, a 60-year-old today would relate to music popular during 1970-1980 and an 80-year-old today would relate to music from 1950-1960. Someone born after the heyday of swing (the Benny Goodman, Glen Miller, et al era), could logically say “‘In the Mood’ puts me out of the mood”. MAYBE folks who have been dancing a long time would relate to music from the time they started dancing (especially if they took a lot of lessons at that time).
