Amazon has a dozen or so albums with the title "Good to Go"; most all are
from the last 6 years and are urban or hip hop music.

If you go through the book search, though, the phrase is much more
associated recently with instruction books (program your computer, fix your
Harley, seduce a woman --  "Do xxxx, and you're Good to Go!"), and as you
move back past the mid-1990's, it becomes more associated with military
themes.
