If you have a CD for which you need copyright protection, you need to convert the tracks to mp3 format, or wav.
You can do this very easily with any file converting software utility.
Do not directly upload from the CD, as those files won't contain your music. They are just instruction files, like midi files are.
Therefore you need one of the above programs to do the file-conversions first.
You may prefer to convert your music to mp3 files, instead of wav, in order to save upload time.
