I’d say there are three main types of music videos; ones of the band (fades and layering of different angles while they play; Story telling; and random (where what you see and hear really have nothing to do with each other.
If the creative aspect of the video is solely on you, I’d try finding a song you like and listen to it a good number of times. You’d be surprised what your third eye will start to see as your brain starts putting its own version of what the music portrays visually.
