Or. Go to your sound card settings and select recording device "What U Hear". Go to Cool Edit/Adobe Audition or similar etc., start recording. Go to Jazz2 and play the level you want. Try to stand away from enemies, they make noise and walk back and forth so Jazz, Spaz or Lori won't disturb the music. You can also plug a cable from speaker to mic port if you can't do "What U Hear"-recording.
