Hi Southpaw,
It seems I managed to screw up adding a bunch of new files (chromecat, missions, and the sound sdef files for the bside)...
We'll make sure they're in the next patch, but if you want to try it before that extract the contents of the attached zip to Mods\aircraft\F14\Sounds\sdef\Walkman and then name the songs BSideSong1.ogg -> BSideSong10.ogg. Walkman.zip
