Britbox is supposed to be that, I think, but I wouldn't be at all surprised if the BBC cannot legally sell iPlayer subscriptions as easily as you'd think because the BBC's copyright library (especially music) is unbelievable[1] compared to most other organizations, so they'd have to make multiple versions of everything on their books to deal with licencing issues. Lots of British shows get their soundtracks neutered because of this when they are sold abroad.
[1] Example: Sky Sports F1 is pretty big budget, but they're still stuck using [knock-off version of The Chain] rather than the real thing, whereas the BBC can break out a really expensive song (e.g. Money for nothing by Dire Straits) for a throwaway segment.
I’m surprised to hear that, because my understanding is that all the major broadcasters have a blanket licence to play all music (from major record labels). They can just stick a top 40 hit in the background of a soap without planning for it. Maybe that doesn’t apply to something as primary as the shows theme song.
I believe that’s exactly the problem - that licence is only good for the UK.
When shows are exported they’ll gut them. Top Gear is the best example I know of, on the netflix & bbc america versions, most the recognisable songs have been replaced by musak.
