The importance of the soundtrack to a movie, video game, TV show, or any other form of media is really underrated, in my opinion.
I was just talking with someone I know who works in audio production, and these guys do not get enough credit for what they do. Same goes for the musicians behind it. Sound and music can make or break the end project, and it really is a fine art.
Call me weird, but I do listen to official soundtracks in my personal time quite often. More often than not, it’s ambience or background music, with no lyrics at all. If it’s good, the audio captures (and defines, really) the mood and feel of whatever media it’s from. Listening to the music on its own brings back a lot of the enjoyment from the entire production, and hearing it separately builds a much greater appreciation for it.
Knowing, understanding, and appreciating ALL aspects of a media production (acting, voicework, cinematography, visual effects, audio, music, writing, set design…the list goes on) is something more people need to do.
