These came to mind from the "Scientific Noise" thread, but since they're not what the Original Poster was asking for I decided to start a new thread.

Notes on the second link:
"From an original CD: JUPITER NASA-VOYAGER SPACE SOUNDS (1990) BRAIN/MIND Research


Fascinating recording of Jupiter sounds (electromagnetic "voices") by NASA-Voyager. The complex interactions of charged electromagnetic particles from the solar wind, planetary magnetosphere etc. create vibration "soundscapes". It sounds very interesting, even scary.


Jupiter is mostly composed of hydrogen and helium. The entire planet is made of gas, with no solid surface under the atmosphere. The pressures and temperatures deep in Jupiter are so high that gases form a gradual transition into liquids which are gradually compressed into a metallic "plasma" in which the molecules have been stripped of their outer electrons. The winds of Jupiter are a thousand metres per second relative to the rotating interior. Jupiter's magnetic field is four thousand times stronger than Earth's, and is tipped by 11° degrees of axis spin. This causes the magnetic field to wobble, which has a profound effect on trapped electronically charged particles. This plasma of charged particles is accelerated beyond the magnetosphere of Jupiter to speeds of tens of thousands of kilometres per second. It is these magnetic particle vibrations which generate some of the sound you hear on this recording."

It's of course important to understand that the sounds presented in your links are not originally "sounds" (i.e. acoustic signals, pressure waves). They are radio signals which happen to be in the right frequency range (or they are converted to such range) that when played through speakers form something we can actually hear. The same obviously applies to any electronically generated sounds used in music/noise and this doesn't make the resulting sounds any less intriguing.

Anyway, actual sounds have also been recorded in space by microphones. See a review/perspective paper on the subject:

Here is a sound sample (first on the list) from the acoustic sensor of the Huygens probe as it descends to Titan:
