I generally prefer to listen to ambient and instrumental tracks while I write, either that or lyrics I literally cannot understand. I find that if my mind begins to wander as I'm writing while listening to song lyrics, I'll sometimes start writing out what I'm listening to, rather than what I'm thinking about.

I'm pretty much in the same camp as this. Of late I'm preferable towards instrumental music or anything with either incomprehensible/giberish vocal lines, or otherwise lyrics that I can't make out due to distortion effects or language barriers. Lately my go-to tracks fall within the Post-Rock and Shoegaze genres, which, incidentally, have felt accurate to the mood for a few characters that I"ve been writing; particularly over in [url=https://www.roleplayerguild.com/topics/195271-heroes-rise-paragon-city/ic]Heroes Rise[/url]. 

Recently, I've realized that I can in fact write without music underscoring the experience. At this point, it's more about multitasking than anything else; there's only so many waking hours in a day, and writing and listening to music (specifically the music that I most enjoy listening to) are two things that I can do at the same time without feeling like I'm shortchanging my attention on either of them.
