All of the songs were AM radio hits back in the 1970s, and the selection spans the whole decade, though most are from 73-77. The most rocking was Supertramp’s “Take the Long Way Home”. Chapin’s “Cats in the Cradle” is a typical selection. One problem I found was some, though few, songs played twice in a short span including “I Go Crazy” back to back. One suggestion is to add some songs that are 70s soft rock but didn’t chart very high such as Oh Daddy by Fleetwood Mac or Oh Darling by Supertramp. Thank you for this app.
