It is funny, I'm just reading this while listening to some favorite radios, and I'm at home just researching business possibilities.
When I'm in the office it is my standard procedure to wear headphones and listening to something at least 3-4 hours daily (sharing office with 2-3 folks and it helps me to focus on my things).
When heard something interesting on radio I'm always about to google it, so idea is good to target at least 40+ audience that still remember old way to fun up a day while work. Could not stand FB thing frankly nor see myself with a selfie stick, so radio is my transparent amusement while work and YT when I want to hear some particular song.
And now days it should not be very expensive to hire one host to cover gaps between songs and read some ads as well ;). Someone could work on this as a side job recording things 2-3 hours per day and schedule all things for 24h time frame.
Good luck with this idea, I approved it
And get back to us in few months and let us know how it is going, I'm also interested so see outcome.
