Ipods are great. I can place the music on my Ipod that I want to listen to, and I don't have to listen to any unnecessary crap, whatever that is. Terrestrial radio doesn't do much for me any more, and it has nothing really to do with the music genre presented. The fact is that radio has ceased to entertain, for the most part, and captivate audiences. This is why other sources of entertainment, including satellite radio, have become more popular in recent years. Couple that with the ability of individuals to download, burn their own CDs, or stuff MP3s into their portable music devices and you have a diminishing effect of radio in society.
And it doesn't help that the major corporations have dumbed down radio to the lowest common denominator.
