I have HD Radio now and for a while now since I had first been introduced to it and I just love it and my husband really likes it because he does a lot of travelling so he gets more stations that he can enjoy when he is in the car.  HDRadio has great quality sound too.. it is not satellite radio though but digital FM and AM radio with a ground based antenna.  And if you want a great product then you have to check out the new Jensen JiMS 525i…well new to me.  This is a nice system and if you like iTunes then you are going to love iTunes Tagging.  This way when you do not know that song that you just instantly fell in love with and you want to buy but you don’t know the name of the song now you don’t have to worry because it will be tagged for you so that when you go to buy it you will know the name of the song!  Cool huh!  And I think the best feature of HD Radio is the fact that it has new music stations.  Check out HDRadio.com for more information on what they can offer for you.
