This is the best background noise app I have ran across. Just play it quietly by itself or layer it with your music for instant local coffee shop ambiance. I have included an interior shot of my favorite coffee shop in the entire world where I am often found reading and sipping.
I find it pretty soothing and it scientifically claims to boost creativity. I found myself several times looking up to see who the cute guy with the voice was and then realized I was still at home. Enjoy. :)
