I had a listen to WII now. It's actually a song that I never took a liking to. I think it's the amount of lyrics; it's such a "mouthful" (no pun intended), so much crammed in that it's difficult to process it all. That said, the music is classic Knopfler as dusty said, even classic Dire Straits. It reminds me a bit of Tunnel of Love to be honest, the way it builds up, subsides and builds up again.
Then again, there's just something cool about Back On The Dance Floor that appeals to me. It may not be a better song, if judged by some objective standard, but if it moves you, who cares?
