I’m a big fan of fip, a French radio service that is franchised regionally but also available over the net. They do fip rock, fip jazz, fip mondiale, fip reggae, and a classical flavour too. There’s also a stream that mixes elements from each of the above, branded simply as ‘fip’, which is what I listen to. Highly recommended, it’s where I pick up most of my new stuff. And it’s ad-free*. And there’s very little speech (on the net version; I believe they have local news on the broadcast, locally franchised, version.)
* this is a major plus for me. Born and raised a child of the BBC, I cannot bear advertising on the radio, or tv.
