If you like rock music from the 80s that doesn't sound like typical 80s rock music (aka hair bands) I'd recommend Kate Bush (and the albums Hound Of Love and The Sensual World, though HOL is easier to get into). I'm a fan of Sigur Rós (Takk or Með suð í eyrum við spilum endalaust - first one is very sweeping and dramatic, second one has more pop to it), which is one of those postrock bands from Iceland. They're pretty good. I'd also recommend Imogen Heap (Ellipse or Speak For Yourself), who I think gets labeled as triphop although I don't quite understand that term, for something more contemporary and creative.
