Depending on your sound card... I know that SBLive and SB Audigy cards have a "record" feature. With this record feature, you can set the input source to "What You Hear"....
Hit record, and play you CD.. What ever you hear out your speakers is what will be recorded...
More than likely, this will be a wav file around 640-650mbs in size. Straight though, no stops in the file.. That's one huge audio file. You can then use various utilities to convert the wav to a mp3.
I hope this helps...
BTW - if you had a audio editing software, you could load each individual mp3 or wav into one file, shove each track end to end within the software, and save it as a single track file...
Just a couple of options for ya...
