I found the below site while browsing some comments in a Reddit thread and decided to post it here.

However I don't think we have a thread for people to post a link to a random web page they might have found while..doing whatever. I'm sure sometimes we won't want to know how you found it.
So please post links to random/interesting/etc. sites here.

This site allows you to see how far radio waves have traveled since they started broadcasting, as well as some of the songs from that year.

As per the website description:
Radio broadcasts leave Earth at the speed of light. Scroll away from Earth and hear how far the biggest hits of the past have travelled. The farther away you get, the longer the waves take to travel there—and the older the music you’ll hear.

Really, really cool site man. Really tight yo!

But I wonder, wouldn't the frequency then change too?
 
Also, you've opened up a whole debate and argument here in my office because of this. Well technically me, but because of you and this website :p

Do you mean change of frequency the further the radio waves travel away from Earth? If so, if not sure and well investigate!

Niahahahahaha!
 
I am sure there will also be a difference weather it was amplitude or frequency modulated?

Anyway - great find!!

Don't know about frequency changes and what not, but that is a brilliant site - nice find indeed!

Though completely inaccurate:
The speed of sound in air.
Sound can travel in air at approximately 332 metres per second. This is fast but not nearly as fast as light which travels at 300 000 kilometres per second. This difference in speeds enables us to appreciate that sound does take time to travel.

Edit: I stand corrected:
Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second. At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second.

Since no one else has (yet) embraced my thread, I also found this website last night.

It starts a while after the Eagle has released from the Command Module and started its descent.

Description on site:
46 years ago, the entire nation watched as three men explored the unknown. Watch, listen, and relive the excitement of the Apollo 11 lunar landing as experienced minute-by-minute by the courageous crew of Apollo 11 and Mission Control.

A tediously accurate scale map of the solar system that illustrates the mind-boggling amount of space between planets.This started as a personal curiosity project and ended up getting posted on hundreds of websites, featured in museum exhibits, used as a teaching tool by science educators, and translated into 16 languages.

Using the autoscroll feature (little icon bottom right at the start of the timeline) which simulates travelling at light speed (!) it took me a little over 3 minutes to travel from the Sun to Mercury. The quotations, comments and bits of info along the way and between the planets are pretty neat, but if you want to skip through them use the planet icons top centre of the screen.

50 light years away some aliens are listening to Beatles, Rolling Stones and Eric Clapton and saying "OMS*! This is amazeballs! Ready the Millennium Hawk. We shall find the source of this delightful sound."

By the time the get within 5 to 1 light years they will hear Kanye West, Lil Wayne and Rihanna and will be all like:

* OMS = Oh my science since aliens have no concept of a god
