Music?
I have yet to experience DAB+ so I don't know whether it will provide an incentive for me to buy a new radio or not. The one I have is always set to FM, except when I use DAB to get BBC World Service. My current plan is that if they ever phase out FM I'll completely abandon listening to music on radio.
Why? Music (classical / acoustic music) on DAB is transformed into ghastly noise, even on a low-fi portable "transistor" radio in a bathroom. It astounds me that so many people cannot hear the difference. Yes, I get occasional interference on analog, but it's transient.
