Nero express

Hi,

Anyone has been using this Nero express? I have tried just burning one audio file, took out the disc, try listening to it. Then try burning another audio file with the same disc, and it is locked! I have waste the rest of the space.
"music=> audio cd => add=> Next => more => then there's this Finalize Disc which is already checked, I can't uncheck it.

Can anyone show me how do I solve this problem by not finalize the Disc. Where's the option?

Thank you.

You cannot burn an audio cd and then add songs later on. The program needs to write a TOC (Table of Contents). This tells the CD Player the number of songs and the lengths, etc. THis can only be done once.

Multi-session?

Not on an audio cd, a data cd yes. But not on an audio cd. Its whats has todo with the TOC.
