When 3.5 jack is plugged in

[clcmbtn]

When 3.5 jack is plugged into my laptop and I plug the other end into the car radio the playlist just keeps skipping from one song to another.  I have been using it this way for over a year with no problems.  Now today its a problem.  With the plug out and listen on the computer everything is fine.  Need help please.
