Free (not paid) internet jazz radio stations

Radio Swiss Jazz. Lots of names I haven't heard, great for listening to new music. Of course if they only play recent music, then you can't really criticize them for not playing older music, but for me I wouldn't mind 1/3 of the music being older music. I've been listening all day and I've yet to see an artist I knew! I mean I know I'm not in Switzerland, but I am in NYC, the big apple was named by jazz musicians, it's the place to go if you're a jazz musician.

Supposedly the most popular band that played in last 60 days is Michel Weber Mike Goetz Swingtet. I love listening to European jazz, but again, the sole focus is perhaps skewed, like the present jazz is skewing. Sam Burckhardt is the second most played artist. I guess you can't fault Swiss jazz station playing what's hot in Switzerland. 

"KCSM's Bay Area service covers straight-ahead and contemporary jazz, including bebop, cool, Latin, vocal, and classic repertoire, with live programming throughout the day. It plays jazz music around the clock. Listen free on muso.fm, no account needed."

This one's most frequent artist is Miles Davis, then Dizzy Gillespie, then Coltrane, though if you add in Coltrane quintet, it's second. They really like Bobby Watson. 

There are sponsor plugs, and it's not quite all jazz, there's blues and R&B. 

ABC Jazz: Australia's 24/7 jazz network features Australian and international artists alongside original performances from ABC programs such as Jazztrack and Jazz Up Late. It plays jazz music around the clock. Listen free on muso.fm, no account needed.

This one doesn't list the artist, or have any stats on Muso.com. And the DJ talks about each track. 

There's a whole list of them.
