I’ve listened to BBC2 a lot in the UK and my description of it would be it is adult music focused with some light entertainment talk and guests, but still playing mostly music every hour. The music is very diverse but at the same time includes a lot of mainstream classic hits and some new music. The music is kind of what I had hoped Double J would evolve into but I still find Double J too random and alternative.
BBC2 have a light and entertaining breakfast show still with lots of music. Then the morning show features call in quizzes with a music focus (e.g. questions on hits and artists from a particular year).
For me the secret is in the music though - it has just the right amount of mainstream classic hits and “adult alternative” hits. A low key and light presentation style. When they do have guests on or do a talk segment it’s never too heavy or too long.
They do a “full service” BBC news most hours especially in the morning and at night they’ll often do a feature hour or two on a particular artist or year - and they can get really obscure at night, especially for a station that is No. 1 in the country.
I really think it would work in Australia but nobody has really tried it here. I think it’s what Vega thought they were doing, but they weren’t. It would be a perfect choice for Talking Lifestyle but they would need to refocus on music and music related talk rather than the current infomercials.
