Those songs were fine...and still are.
I sometimes refer my students - generation born in the 70s and 80s mostly - to Motown music - and they always say how much they love it and wish it could come back.
No one rational couldn't love it.
My seven year old LOVES it!
Sweet, easy to dance to, nice words and message.
Compared to today ... I now understand why people get in time warps when it comes to music. Todays music is trashy.
