Hey, I just downloaded Radio365 Beta from Live365's website at
http://www.live365.com/downloads/rad...mac/intro.live and it works great so far
Basically, it is a standalone ap that offers you a choice of all 5,000 + (or something like that) of Live365's stations, which collectively play pretty much every type of music ever created by humans or computers.
You can search the stations for artists, tracks and albums they play and each track played on the ap links to the relevant album in itunes music store.
it's a really slick cool application exclusively for mac users (from what I can tell) and it has definitely made my workday more enjoyable!
