I think it's a start-up/hobby for someone who used to be in radio. The fact that they're only on for limited hours tells you what you need to know. And of course, you don't have to give them anything to listen. But I think what they're doing is interesting. What happens when they've played all 15,000+ songs remains to be seen.  

I'm a bit disappointed that they're not playing them in order, but then that wouldn't necessarily leave them with a variety of eras to spread throughout the day and would only encourage tuning for "your era." 

Plus, there were tons of songs that were only hits in Britain and never made it over the pond. So there may be some wonderful stuff we've never heard here, where you can discover, in effect, "new oldies." 

Here's what the About Us page says about the newcomer, indicating that when they're finally finished, they'll start all over again. 

"Retro Charts Radio was launched to provide listeners with a historic archive of all the UK Top 40 hits from the start of the music charts back in November 1952, right up to the last chart of 1999.

By our calculation there are 15,275 hits from that period, which will play randomly each day between the hours of 8am and 11pm. There will be no presenters, no shows, no news, no playlists, no favouritism and no exceptions. No frills, just the music!

With our elimination random system, every single hit will get a chance to be played before the whole process starts again, enabling us to give you an ‘8 Week No Repeat Guarantee’!

As you listen, you will notice that there are literally thousands of hits that you have never heard before and even more #HitsThatRadioForgot. From Bing to Bowie, Sinatra to Sinitta, Fury to Ferry and Stargazers to Starship, we have them all.

Our ‘Now Playing’ feature will also display the year of chart entry and its highest position. Fascinating facts nobody else provides on such a feature."
