This site is basically a bunch of very mellow youtube videos, all embedded onto one page. Combined together they make one big awesome ambient song, all in B flat. It's really quite relaxing to listen to.

May be laggy playing all of them at once if you're connection isn't good enough.

That is actually pretty relaxing. Darn near crashed my computer though, lol...I didn't read that you don't have to play them all, just some.

That was really cool! I love how it actually meshed together no matter what order I played them in. Good find Sir!

Yeah, great find. It wasn't completely harmonic in the order I started them in, but it certainly wasn't dissonant either.
