Motown, really, is kind of hard to define. It was probably one of those “you had to be there” moments in history and most of us weren’t, which makes it even harder.
Motown originated in Detroit of course, and in many ways the music was put together in assembly line fashion. Songs were written by teams and assigned to groups, musicians stuck to the plan and records flowed out of the Motown “factory” like clockwork.
And there are so many great performers that came out of Motown that you could listen for days and days without repeating anything.
