I want to make a CD from all the some of the (paid) music that I havd downloaded. The formats they are presently in are .wma .wav and .mp3. 1. What format do they have to be in for me to burn it to a CD and listen to it on my car player? 2. How do I convert it to that format? 3. Can I use and ordinary CD disc or are there special discs for music?
