Her music has also been heard worldwide from 1986 to present, as part of several high-profile product campaigns, with corporations such as Mitsubishi, Epson, Yamaha, Toshiba, and Chevron being among the many to utilize her original works.

Being anonymously responsible for a number of musical wakeup broadcasts to Space Shuttle astronauts from NASA's mission control during the late 1980s through the early 90s, earned Cunningham the nickname, "The Most Flown Unknown".

[citation needed] In 2002, Cunningham was commissioned to write, record and perform a tribute song to the United States in commemoration of the September 11 attacks for the country of Aruba.

After touring internationally with the all-female band The Cherries, Cunningham began building her own recording studio, Resnik-One (named after astronaut Judith Resnik who died in the Challenger disaster), in Los Angeles.

During this time, she also attended the American Academy of Dramatic Arts, developing her acting skills with the intention of one day performing in musical theatre.

Between tours as a guitarist with Lionel Richie's band and as an opening act for David Crosby, Cunningham continued to hone her skills as a songwriter, including writing for high-profile international corporations.

In 2007, after a six-year dedicated effort, Cunningham completed 23 compositions for her first musical, DULA (from the play written by Paul Elliott), which gives a detailed and dramatic history of the folk-song legend Tom Dooley, presenting him as an innocent man who was hung for a crime he did not commit in the years immediately following the Civil War.
