To me the Miami Vice series was the formative pop event of the decade (Jan Hammer and a cast of thousands.) Advert soundtracks never really looked back. Mike Nesmith gave us the movie (and soundtrack) Tapeheads as commentary. Best Roscoe's chicken & waffles commercial ev-er.

To the others mentioned above I would add:
The entire Doug & The Slugs catalog save Terminal City ('92)
Randy Newman – Trouble in Paradise (I Love LA = pop anthem) '83
