One music video he did was 'OMG' by Usher featuring Will.i.am

The video begins with Usher flickering on a television in a room which is a reference to Max Headroom, a fictional artificial intelligence character from 1980's British television and film. We then see him dancing with blue flashing lights, and will.i.am. is shown in a similar room with red flashing lights. Maybe this represents a battle of the elements. Usher is then shown with female background dancers in a white room. In the scene he dons a pair of glasses which show the dancers performing through the lens. Usher then dances outside in front of a concrete wall, with male background dancers appearing as shadows. As will.i.am. performs his verse, he and Usher are seen in their corresponding rooms with flashing lights. After this, Usher puffs a cigar and dances with male background dancers in an arena-like area, whilst he is also joined by female dancers with flashing lights on the floor, with the video ending with Usher shown on the flashing television as he was in the beginning.

Another was 'I Knew You Were Trouble' by Taylor Swift

The video starts with Swift speaking in a confessional voice-over. Swift wakes up on an abandoned desert, surrounded by trash and debris, and wearing dark makeup. Flashbacks show Swift and her boyfriend engaging in various stunts, along with a few tender moments, such as when Swift's boyfriend gives her a necklace as a gift. After a while of what seems to be a good relationship, she begins to realise something is wrong. While in his parked car, he leans over to kiss her when police pull up for him. He starts a fight in a club, which results in the both of them being injured. There are also scenes of her in a grimy small bathroom, looking at herself in the mirror. While at an outdoor concert, she sees him kissing a large number of different girls. He then looks at her in a nonchalant fashion. She falls asleep in the desert where the party is being held, and wakes up alone the next morning. The video ends with her letting go of the necklace he gave her.

A Third Is 'Ride by Lana Del Rey

Opening with an image of Del Rey swinging on a suspended tire, Del Rey narrates: "I was in the winter of my life and the men I met along the road were my only summer." Further into the narration, Del Rey expresses how she found sanctuary through traveling, while on tour, because the singer had not had a proper home for a long time. She also expressed that her dreams of becoming a poet were crushed and eventually opened the doors necessary to begin a career as a singer. Following the confession, Del Rey is seen riding on a motorcycle, flanked by a clique of leather-clad bikers and wearing anovelty t-shirt that reads, "Buttwiser: King of Rears." Other scenes include Del Rey wrapping herself in an American flag; another depicts her in sexual poses with an older man playing on a pinball machine.

A Fourth One is 'First Love'  by Jennifer Lopez

The black-and-white music video starts with Lopez exclaiming, "I knew I had to leave the world behind me to find out who I was," as she wanders the Californian desert in her finest couture gown. "I knew that love would never search for me, that I would have to search for it." Later, the video sees Lopez (wearing a clingy white bodysuit) and an male actor in love scenes.
