Before I even knew that this song is entitled "Intergalactic", I've heard it, especially the robotic-voiced lines "Intergalactic, planetary, planetary, intergalactic".
I finally knew the song after looking into some of the songs at an Australian radio station's—Triple J's—Hottest 100 of the Past 20 Years in 2013. This is the 100th track.
Some research informed me that this piece consisted of many samples and elements derived from other musical pieces. "Intergalactic" now looks like a jigzaw puzzle for me.
