'Tiger Tiger' by Duran Duran. Mainly for the bassline, but also because every time I hear it it evokes a beautiful sense of loving nostalgia. Not for any reason, that's just the effect the music has on me. It's extremely calming and wonderful. ~nods~
'Tel Aviv', also by Duran Duran. I've never heard anything that sounded anything like this, it's really *very* strange, and as part of the band's first album it's perfect, contributing to that slightly eerie, alternate-dimension feeling most of the songs on it have. And it has violins with synths! I love violins with synths.
'Astradyne' by Ultravox, for sheer unparallelled synthesised star-reaching glory.
And for less listable reasons, also :
'Rose Arcana' by Arcadia
'Leopard Ray' and 'Still Waters' by The Thompson Twins (they did two songs called 'Still Waters' but only one's an instrumental)
'One Of Our Fruit Machines Is Missing' by Nik Kershaw
'South Downs' by Roxy Music
'Down In The Park (Piano Version)' by Gary Numan
