I strongly recommend a program "MP3 CD Builder" it can create audio cd's from MP3s that play in your home or car cd player! No need to convert from MP3 to WAV; it burns directly from MP3s! You can have a try from http://www.mediasoftzone.com/Audio-MP3/MP3-CD-Builder.html Holp it helps!
CD-R discs are what you want to be using to burn CD's to play in conventional cd players. they can be bought for cheap enough that you dont need to use CD-RWs.
Also try burning at a slower write speed - i have found this helps with many cheaper lasers
