I'm trying this out now and am really enjoying it. I work at home and usually just have my noise canceling headphones on with no music playing, so having the ambient coffee shop sounds plus music is a nice change. So far, I'm still able to concentrate on my work. Not sure if I'm being more productive or not, but it is a nice change. I just need a coffee to complete the illusion.

The loud dish clanks don't really bother me yet. (I am using my beloved Bose Q15 headphones, listening to KCRW Eclectic 24 + the ambient soundtrack both volume levels are very low).
