Speaking of streaming, when I first got hooked on iTunes, the radio feature was just a collection of various streams from around the web. When I upgraded to iTunes 11, the radio feature was changed to be more like Pandora Radio. There are several genre-focused stations. Or you can play stations based upon artists. Since I like modern lite AC, I selected a station based upon Josh Groban, one of my faves in the modern lite AC genre. A station based upon him has brought up artists such as Enya, Michael Buble, The Canadian Tenors, and even some of today's country crossover such as Faith Hill and Carrie Underwood. Just like with Pandora, you can customize what songs play on the station. iTunes Radio is ad-supported. If you subscribe to iTunes Match, which is $25 a year, you can listen to iTunes Radio ad-free. The customization factor is what I love about these streaming services.
