I've been burning music through rhapsody, but found that I can't play those CD's in my car's CD player. I'm thinking it's because the cd is made up of .mp3 files and the player can't read the disc. How do i burn an audio cd that is compatible with all players and can be played anywhere? Is there a 100% free cd burning software I can use? I want to give my friend a cd but i'm afraid it won't play in his car either.
