Pandora; a threat to everyday radio?

As a recent passenger on the Pandora flight, I have to say, Pandora has the potential to be a pretty strong competitor against AM/FM radio. If you haven't already registered, I suggest you do!
Pandora is a website where you enter in a song or artist into it's search engine in order to start your own custom playlist. (I say playlist because Pandora calls it a station but the music is flowing song after song.) If there is more than one option for your search they are all listed for you to choose from. You select your preference and "voila," a window of opportunity is opened. After the first song, the one you selected, concludes, Pandora provides you with song after song of similar tastes. Fortunately, if they pick a song that you don't like, you conveniently give it a "thumbs down" and on comes the next song which Pandora thinks you will enjoy. Furthermore, if you really like the song that comes on, "thumbs up" it is. All in hopes to create a station Pandora knows you will enjoy.
Pandora provides listeners with a randomness of songs yet a similarity that strings the songs together.
For many, this is better than AM/FM radio. Where we all have our favorite radio stations, we still at times have to suffer through the songs that are played that we don't like.
Over Am/FM radio, Pandora supplies a skip option where if the first five seconds, or even the first two seconds, of a song you don't like comes on, you don't have to suffer even one more second. All you do is skip it!
An additional option, a song comes on that you like but are a bit sick of at the present moment; Pandora offers the option to select "I'm sick of this song." In return, Pandora will not put this song in your playlist for the next 2-3 weeks.
If you don't know where to begin the site also has different genres to choose from to get you going. AND if you're not near your laptop, Pandora is offered on most smart phones. Pull out your blackberry and right away you have a portable radio guaranteed to satisfy any individual's taste.
The Pandora pandemonium isn't effected by radio wave regulations and restrictions. It is not effected by the hardships of trying to market diverse groups of people. Pandora may just be the actual threat that XM and satellite radio tried to be. Pandora is going places, jump on for the ride!
