If we are getting into Alternative sources. A Squeezebox is another nice little device to explore Internet radios. They key is to explore lots of stations in the desired genre to find the particular stations that not only play what you like, but also sound good. There is a big discrepancy among the quality between stations. Some are poor but others are quiet excellent, considering ho it gets to you. Best of all, free, other than the cost of the Squeezebox, which is also handy for playing your digitized music collection.
