Looking for a movie of about futuristic city and alien society [closed]

I can't describe the title well.So, maybe it's a bit confusing. Anyway, I am looking for this movie. I watched it maybe around 10-15 years ago. These are what I know about it:

Year : I guess it's from late 80's to late 90's. It's not black and white

Genre: Sci-fi. Some comedy and action. Not animated

Plot:
The movie sets far in the future. Alien is not an usual thing there. There are a lot of hi-tech things, from flying cars to a battleships. There is a spaceship war going on and the enemy looking for a specific thing/person. The protagonist works as a courier(?). There's also a scene of which aliens visiting pyramids (I think it's in the beginning of the movie). There's a blue haired black guy that works as a MC. There's a shoot out during the show and an alien singer is killed.
