"...originated by radio programmer Bob Perry on his on-line radio
stream called 'Jack-FM' in 2001. Perry, who uses his on-the-air name
"Cadillac Jack Garrett",  experimented with throwing together a list
of Top 40 songs from different periods and music genres and playing
them in no particular order".
