After 10 years working from home, I've noticed some strange correlations in my productivity. In particular, I am far more sluggish and unmotivated when I forget to put on some music (and when I forget to open my windows). It seems small, but some good background jams can really make a difference in the work you get done. This isn't just anecdotal, either--plenty of research actually suggests music can help you get into that "flow state" required for more productive work, particularly fast-paced instrumental music that doesn't distract you with lyrics. It turns out, there's a genre of music that fits this bill perfectly: video game soundtracks.
