On my older computer where I store all my music, I have the free version of Sonic record now as well as Windows media player. These programs enable me to burn my MP3 files to CDs that will play in the car or home stereo. However, the home recordings I make will not play on the CD player at my yoga studio. I lead a meditation group and would like to be able to play my meditation MP3's at the yoga studio. I don't know why the CD player at the yoga studio would be different than my car or home CD player, but it is. I am thinking that I might need a program to convert the MP3 files to CDA or some other format. Any suggestions? PS...My newer compuier has Roxio Creator basic V9.
