Okay so.... last night I popped Black Ops in and decided to put on my headphones and instead of listening to the game audio leave them plugged into my PC and listen to my Spotify playlists while I played. I found that I ended up doing pretty well and often placing in the top 3 on a pretty regular basis.
Before work I ended up playing and played with the game audio and the game had my full attention and I ended up doing worse and getting slightly frustrated.
Am I alone in this? If I don't care about winning it seems I end up winning more than when I'm focused and trying to win.
