Creative's sound drivers have a very useful feature - in addition to recording from microphone or aux-in you can record "What U Hear" and capture whatever is playing through your sound card. Combine this with Creative WaveStudio and an MP3 or Ogg encoder and you can record anything you're able to hear on your PC.
This is much easier than the contortions I went through trying to record a RealAudio stream via Total Recorder. Great for recording game soundtracks. And it's a simple solution for bypassing whatever consumer-hostile DRM crap the rest of your computer tries to foist on you.
