I don't imagine that there are any ideas what the Radio Scotland music station would cover, but would it be Scottish music, or UK / international music with Scottish presentation around it?
I can see the argument for talk more than music, as surely Scottish musicians are covered by the existing music based BBC national stations?
As Inspector Sands said, it would likely to take a similar format to Radio Scotland Music Extra which ran for the week up to St Andrews Day. The station was a little bit rusty around the edges, but it had great potential. I don't think a full-time station would go 100% Scottish music, but a 60-40 rule, as is the case with most French radio stations would give it that point of difference over commercial rivals. The big selling point for me during the trial was the sense of it being a credible, 'grown-up' radio station. It felt like a less pretentious 6 Music. Lots of new artists, great Scottish bands and musicians and some good interviews.
I've spoken to a few friends in commercial radio and they're actually quite excited at the prospect of its arrival. Deregulation carries a risk that most Scottish programming could - at least legally - be lost, so the BBC providing Scottish music content could force the hand of commercial broadcasters to stick with Scottish content, raising the bar while also offering listeners more choice.
All-in-all, some good progress for Scottish viewers and listeners.
