Top 25 Music Videos of 1989 (I've seen)
Not listed:
(though most are often placed in similar "best" lists)
Aerosmith "Janie's Got A Gun", though a serious song/video, far too dark for my taste. Motley Crue's "Dr. Feelgood" is dark, but the video isn't graphic. Oddly, the alternate version on the DVD only features the band performing.
Madonna "Like A Prayer", catchy song though the video's too overrated and pretty much done for shock value
Metallica "One", The songh's OK, though not actually an 'all time' favorite (the guitar solo is great), though the video's pretty much scenes of "Johnny Get His Gun" and the band performing.
Milli Vanilli videos, because they're plain awful (I find "Baby Don't Lose My Number" hiliarious) 
In no special order since I don't exactly have a personal #1 video for that particular year
