To be honest, I still don't get the hype about Sultans. It's a damn long (6 minutes almost!), repetitive, "boring" song. When I tell people, regular folks, that I have a channel with Mark Knopfler & Dire Straits music, they sometimes Google it right on the spot and take a listen, and when they hear Sultans it's clear to me they don't get it at all, and Sultans is clearly not the type of music they would want to hear, they just fall asleep listening to it. It has cool guitar licks in it... Aaaand?
Still, I think without Sultans, Dire Straits would be huge. Songs like Brothers In Arms, Money For Nothing, and Your Latest Trick alone are enough to launch any band into the stratosphere. MK&DS are not a one-hit wonder, luckily. But when you compare the popularity of Sultans against all other songs, you can think they are indeed a one-hit-wonder. I remember the poll on the MKNews website with favourite songs, and Sultans got more than half of all the votes.
