Here's late 1970s footage showing a typical American music records store. 

Begins with a high-angle shot of inside the record store. A number of customers are browsing records. A shelf of records is labelled "Popular Rock & Roll." 

A hand flips through singles or LPs. A woman wearing shades looks at records. 

Shots of a few records, including "The Carpenters, A Song For You" and "Shaun Cassidy, Da DOO Ron Ron." An old cash register is used.

A older man browses through records. Before him is the sign, “POPULAR STANDARDS.”

We then see albums of The Beatles’ “A Hard Day’s Night,” the Carpenters’ “Close to You,” Elvis’ “Let’s Be Friends,” Peter Frampton’s “I’m In You,” and Kiss’ “Love Gun.”

A section of the store’s inventory is labelled, “CLASSICAL.” We see the albums of Van Cliburn’s “Beethoven Sonatas,” Artur Rubinstein’s rendition of “Moonlight Sonata,” and Tchaikovsky’s “The Nutcracker” with Eugene Ormandy conducting The Philadelphia Orchestra.
