Show HN: Plant trees while you sleep (thissongplantstrees.com)

A year ago I uploaded a short (31 sec) audio clip to Spotify. Its streaming royalties go towards tree planting.

So far it's been streamed 1.4 million times and we've donated 14,000 trees.

Now we're expanding to white, brown and pink noise. You can play it in the background while you work, study or sleep.

I like to have background noise on while I sleep.

It blocks out distractions.

Streaming for about 2 hours will plant 1 tree

So an 8 hour sleep will plant around 4 trees. A good excuse for a lie-in
