Star Wars easter egg in Spotify when playing disco version theme song

Funny discovery of the day. While doing a small walk down memory lane and reading up on Space 1999 (aka. Mondbasis Alpha 1 in Germany) I discovered that the German version of the series used a disco version of the Star Wars Theme by Mech in one of their episodes.

Playing the music on my desktop on Spotify I couldn't stop smiling when I saw that the progress indicator had turned into a light saber that was even modulating its glow when I moved the mouse over it. That's a easter egg built into Spotify obviously by someone who is a Star Wars fan. Ah - and by the way, while the disco version of the Star Wars theme is certainly a nice 70s disco dance floor piece, the "Other Galactic Funk" is less cheesy a bit more hard core funky stuff...
