CD burning - help needed please

I have to courier a CD to a duplication house today for short run of 50 CD's

Unfortunately, I just installed a Windows 7, and don't have any burning software yet (I used to use Nero). Am I crazy for thinking about using W7 to make an audio CD for duplication? Any hints or tips?

Also, what burning software should I get (for a project studio)?

Thanks, and I know this isn't a very "slutty" question, but I'm in a bit of a bind.
