Thanks for the link, but it doesn't work for me.
I used to listen to nujazz, downtempo, IDM and classic jazz (swing through bossa nova of the 60s) radio stations on iTunes about 7-8 years ago, but since I have accumulated a pretty vast iTunes library of music I pretty much just listen to my own playlists. I can listen to literally a month worth of music without repeating a single song.
I finally also deleted my Pandora app on the iPhone because I just wasn't using it any more due to the vastness of my own music library. True, Pandora and radio in general help you discover new trends and new artists and, perhaps, artists who you never gave a chance in the past, but I am finding I am quite set in my ways now...
