Everything I Need is a song by US singer and songwriter Skylar Grey. It’s the end title for the 2018 superhero movie, Aquaman  (《海王》). The director of the movie, James Wan, asked Grey to write a song for the film. He wanted her to focus more on the romantic part of the movie, and make it more of a “Celine Dion Titanic” song. So we can feel the deep love from the lyrics and Grey’s sincere (真诚的) singing.
