Having been a keyboardist for over 20 years now..I can attest to the difficulty learning seemingly "easy" hooks can sometimes be. The list below is a combination of my favorite hooks, and hooks that are recognizable to NW fans within one or two notes:
Alphaville--Forever Young
Thomas Dolby--Europa and the Pirate Twins (or One of our Subs)
Simple Minds--New Gold Dream
China Crisis--King in a Catholic Style
DM--Get the Balance Right
Men Without Hats--I Like
INXS--Original Sin
Gary Numan--Are "Friends" Electric
Camouflage--The Great Commandment
Heaven 17--Geisha Boys and Temple Girls (especially the intro)
Berlin--The Metro
Ultravox--Reap the Wild Wind
Yaz--Walk Away from Love or Situation
Japan--Gentlemen Take Polaroids or Adolescent Sex
Pseudo Echo--Walkaway
Blancmange--Living on the Ceiling
Many others I'm sure, but these are songs I loved learning how to play
