Music and sounds to support concentration and productivity

I use music and sounds during work for 2 reasons:
1. avoid distractions from noise in the office. That works best with a noise cancellation headset and if sounds are used which drown out the noise (e.g. the forest sound below is pretty effective for human voice)
2. help to get into the flow

So here are some sources which I use:

Sounds

These sites allow to create and share sound environments which are continously looped and randomized. You can also download the mixed samples.
