Feedback Suggestion, MP3 Archive

I don't know if this already exists, but how about having an archive with downloadable MP3s (preferably free) or links to such? I mean with white noise, water sounds, etc.

You can of course find them on Youtube, but I for one can't turn off my android screen and keep Youtube running in the background, and for some reason I don't like the fan sound from my computer should I use that instead.

 

Thank you! I tried white noise for the first time last night and it was truly great!

 

I downloaded it onto my phone and leave it playing

 

Yes, it already exists: http://www.ata.org/sound

Not only can you mix a lot of different soothing sounds (you can even choose the sort of birds in the background if you want some) but also you can export the mixed sound to a .wav file. And every device that plays sound can play a .wav file.
