Internet favorite music service Pandora is exploring the possibility of being built into cars.

If you aren’t familiar with Pandora yet, you need to be.  It is a free streaming music service that allows you to create “stations” by telling it a song or singer/group you like, and then it plays a song to see if it has the correct song for you.  Once you have confirmed the song, it will begin streaming similar compositions it thinks you will like in a similar vein.  It is a great way of discovering music you’ve never heard of and keeping you entertained for hours on end.

Pandora has long been a favorite around the StarterTech offices, and while I personally use the BlackBerry application to listen on the go, playing it in the car hasn’t always been an easy proposition due to hooking it into my stereo via a cassette tape adapter.  Well, things may be on their way to getting considerably easier to listen to your favorite stations in the car.

According to GigaOm, Tom Conrad, chief technology officer of Pandora, was speaking at a panel at the SF Music Tech Summit and brought up that the company is exploring the possibilities of forging deals with auto makers to integrate the service into dashboard displays.  The service is already available in some models of Ford cars, but now it is looking to expand beyond that.

There was some mention of the cost of the service either being included in the car’s sticker price, or possibly bundled with other services.  While we said above that the service is free, Pandora has been exploring subscriptions for accounts that use the service for more than 40 hours a month, and if this was included in your car, you could easily exceed that amount depending on the length of your commute.

No timeline was mentioned as to when this may start appearing, but some hints were dropped that there may be some form of announcement at the Consumer Electronics Show next month in Las Vegas.
