Sure, if I'm the only one interested then it's not worthwhile. It's up to Bill and Rebecca, and how many people they think might be interested vs the effort. I'm just putting it out there.

I'm the wrong person to name tunes - Bill is the one for that. But how much music has been recorded in 20 years? A LOT. Given increasing population numbers I assume more than the 70s and 80s combined. How many songs suited to RP? That's another question for Bill as well... sorry to push it all onto him :-)

I like having the different mix options, and would like to suggestion a fifth - the "Modern mix".
The idea would be to play the usual eclectic mix of music, but from within a relatively recent time period. Obviously that's open to interpretation - I'd like to suggest the last 20 years as a starting point. A lot of music has been made in that time, and it would be great to have a radio station that plays across the spectrum of it. I've nothing against the great music from the 60s, 70s, and 80s, but this could be an option where that music doesn't dominate, and I suppose might appeal to a younger audience.
Anyway, that's the suggestion!
