CDBurnerXP allows anyone to burn kind of CD, DVD, even Blu-Ray for FREE.  The three most noticeable features are creating Data CDs and DVDs, burning audio CDs, and burning ISO files.  With more than 400,000 downloads at download.com, I can definitely say CDBurnerXP is a competent tool in which anyone without a burning software should have.  Here are the list of features:
