Anything XTC released in the 80's is very good. Actually, pretty much everything they have recorded in their career is outstanding. They've got everyone else beat when it comes to writing a good 'pop' song, IMO. They're very underrated though.... it's sad, actually.
I'm pretty sure these are from the 80's (songs I've always liked):
The Fixx - One Thing Leads To Another
Aldo Nova - Fantasy
Loverboy - Everybody's Working For The Weekend
38 Special - Fantasy Girl
Devo - Whip It
B52's - Love Shack
The Romantics - What I Like About You
