I usually turn the thunder and lighting on and listen to this too: https://www.youtube.com/watch?v=CTVraVgzC9U

Maybe not quite so peaceful :)

Edit: My mistake, I'm normally on http://raining.fm/

I cannot even tolerate rain... I need noise: http://simplynoise.com/

... with noise-canceling headphones. I just discovered these a couple of years ago, and I was - am still! - positively shocked at how well they work.

Can you say which brand/model left you positively shocked? I'm still skeptical of those and would love to be proved wrong.

Bose QuietComfort. They're really expensive ($300), but one of the few products I find to be worth the seemingly ridiculous cost.

I listen to bird song, as it makes me think I'm outside in the Summer Time:

Thanks for this, my office is often loud and constant music gives me headaches or distracts me so I'm always excited to find some alternatives.

Sorry for the late reply - You're most welcome, my girlfriend showed me this 6 months ago and I'm a convert now, to the point where I find it difficult to concentrate without it and I have to keep my window open at night or everything just feels wrong.

I hope you enjoy it, I know I for one find it hard to focus with music in my ears, I've even tried Beethoven at one point but nothing gave me the right vibe.
