I think the trend in the industry is to just simplify it into "Music for Media." This encompasses Film, Games, TV shows, Web junk, etc. Basically, if you are writing music for anything beyond pure music, everything falls into this category.
I'm so glad this section of the forum now exists. I've been getting into writing and submitting library tracks recently, and am glad to see another place where we composers can put our heads together and figure this stuff out.
