Nero 8 has a feature 'Audio Ripping' (you can see this option in left hand side havigation). You can use 'Audio Ripping' to convert Audio CD to MP3. You will see the option to give 'Target Directory' where you can store the converted files. In this case, you will see 'Rip' button (as you see 'Burn' in Burn Audio CD process), which you can click and start Audio Ripping.

If you want to burn CD for your important data then, first option 'Data Burning' in the left hand side navigation will do it for you. It's an easy interface provided by Nero. Easy to learn and use.
