Xanadu is just wacky. I tried a year or two ago.
1980: My brother (with a serious hi-fi stereo at the time) had the LP soundtrack and it really grew on me. I was more into early Rush 8-tracks, but this was something different, even to what he normally listened to (Beatles, Floyd, Zepp, Doors, Styx, etc.). In fact, I attribute the ON-J side of that album for developing a...softer side, which would soon serve me well.
1984: First time at future wife's home I see Xanadu on Betamax. "Cool, I like the soundtrack, you like the movie, let's watch it!"...................."What the?!" <still scratching head over this one>
I still like the soundtrack, though. Olivia sings like an angel.
