As the title mentions, the Music unique to Old World Blues is constantly playing, I have no radio set on my pip boy and music is muted in sound options.
I have a feeling it's linked to a problem I posted elsewhere but no one seems to be having this issue with Old World Blues music.

This is my other topic to do with lag spikes with certain energy weapons in OWB
