Another good one is The 1920's Radio Network:

It is also in Itunes Radio under Eclectic. Itunes app, not the lame Itunes store.
Also Gotradio – Big Band and Swing, in Itunes under Golden Oldies.
Actually there are several good stations in Itunes Radio. This is the only thing Itunes is good for - internet radio. Yes Itunes is a horrible Windows app - ugly, clunky and does not follow the Windows style since it brings along all of the crappy Mac/OS X look and feel, which of course, being Apple, you cannot change.
But it works, at least for finding/streaming net radio.
