Mark Knoplfler has been one of my favorite artists for years. I would be certain to have at least Sailing to Philadelphia and Shangri-La. Then, if you don't have them yet, Get Dire Straits' On Every Corner and Brothers in Arms. I use the first one as a reference disk when listening to new gear. There is also a new complation album out this month - The Best of Mark Knopfler and Dire Straits
