Music rights are a bit of a mess across the Atlantic. PRS/PPL licences don't reciprocate with the American equivalents and vice versa. Either it's two sets of licences (and possibly legal entities) or you end up geo blocking. Though on the up side you can stream to parts of Europe and even Australia from the UK IIRC.

Licencing bodies are also fairly actively monitoring these things. I've had them try to chase me for royalties for services that have been shut down because they're still listed in public directories.
