miniRadio para Mac

Another free alternative, as long as you can look up the stream URL, is the 'Web Radio' Safari extension. Elegant, hides away when you don't want it, works great: http://safariextensions.midwinter-dg.com (HINT: Find stations you like in iTunes; Start them playing; Right-Click on the player sub-window at the top and 'Get Info'; At the bottom of the 'Summary' tab will be the stream URL; Copy it using another Right-Click and 'Copy URL'; Paste it into Web Radio and name the station).

FStream works with 10.6 too and is free. I've used it for years!

I use http://radiotime.com/index.aspx?z=634027140025293750 it's free. Hate purchasing thru the App store because there should be a try before you buy edition.

- miniRadio will pause if you put your computer to sleep What else could it do when the system's sleeping? :)
