The Jackson 5: I Want You Back
The thing about the perfect pop song is how infectious it is, how even if you want to not like it, it will find a way into your veins and make your toe tap without you realizing it, or have you humming it on the car on the way home from work. There is perhaps nothing as saccharine and infectious as the hits the Jackson 5 were putting out in the 1960's and 70's on the Motown label.
"I Want You Back" was released in 1969 with lead vocals by a preteen Michael Jackson and was one of their biggest hits. It is a perfect three minutes of toe-tapping, head bopping joy.
