You will be sad to know that I used this track for a personal project a couple of years ago, and today an ambient band requested Soundcloud to remove my track because I stole their music (which happens to have a thunderstorm that sounds exactly like yours). I am so disappointed at humans sometimes.
I'm sorry I'm just getting around to this, but I used this sample in an NPR piece about being Bipolar. It aired on about 200 stations a couple years ago. <a href="http://www.ttbook.org/book/aubrey-ralph-bipolar-disorder" rel="nofollow">http://www.ttbook.org/book/aubrey-ralph-bipolar-disorder</a>
You'll hear it in the last quarter of the piece.
And, for the same show, I'm using this again in a piece about sailing on a tall ship (US Brig Niagara) that will air later this year.
