Weekday programming consists of Russian pop music and talk shows as Davidzon Radio, named after the station's co-owner.

The signal is directed at Midtown Manhattan, as a consequence of protection requirements to adjacent-channel stations to the northeast and southwest of the transmitter site.

In the 1950s through 1970s, the station played Broadway and Hollywood show tunes as well as instrumental and vocal easy listening music.

[citation needed] WVNJ AM 620 had evolved into an all-adult standards format by the early 1970s, playing artists such as Frank Sinatra, Benny Goodman, Mills Brothers, Barbra Streisand, Tony Bennett, Ella Fitzgerald, Ray Charles, Andrews Sisters, Nat "King" Cole, Peggy Lee, Artie Shaw, The Carpenters, Vic Damone, Sammy Davis Jr., Connie Francis, Patti Page, Johnny Mathis and Dinah Shore.

[citation needed] At that point, WVNJ 620 picked up the beautiful music format for night-time hours while keeping big bands and adult standards during the day.

Ratings were low on WVNJ 620 due to the fact it had a weak signal and AM 1130 WNEW was also doing an adult standards format by 1981.

From 10 a.m. to 3 p.m. weekdays, WSNR featured a big band show produced and hosted by Danny Stiles, playing only music from the 1920s, 1930s, 1940s and early 1950s.

[citation needed] Orthodox Jewish talk radio host Zev Brenner uses WSNR for his Talkline Communications network.
