I mean music videos that have nothing to do with the music and mostly just do their own thing and tell their own story.
An example --
Basement Jaxx's Red Alert seems to be about a meteor-worshiping cult awaiting the arrival of their rocky messiah in some unsuspecting greasy spoon cafe in the middle of nowhere.
Once the meteor crashes into Earth, everyone gets horribly mutated and convulses to the strange rays exhibited by the meteor. The infection seems to be localized entirely within the cafe. The End.
Edit: Please link to a video, or at least summarize the plot.
Edit2: Please actually link to a video, or tell me why the video plot is cool. Come on, it's just 30 seconds of your time.
Telephone by Lady Gaga ft. Beyonce. The song is about not answering your phone in the club because you're dancing. The video is about Beyonce breaking Gaga out of prison and then tracking down and murdering an ex boyfriend. It also has some top tier crazy Gaga costumes including a set of shades made of lit cigarettes. Good track if you like dance-pop as well!
