So I have this new cd player in my car. It also plays MP3's. Only problem is, the music files need to be converted into MP3 files before you can put them on a disk as MP3 files, and I simply don't know how. Media Player doesn't seem to have a function to do this, and since Media Player is the only such program I have on my computer, I am rather clueless at this point. Any advise you guys and gals can give me will be appreciated.
