Composition
"I Think I'm in Love with You" is a dance-pop song, with a length of three minutes and thirty-five seconds.

The song is written in the key of A major, with a chord progression of A–E/A–A–E-D, and the song is set in common time with a tempo of 106 beats per minute. The vocal range spans from D4 to F♯5.
"I Think I'm in Love with You" was the first of Simpson's videos to have a solid plot line. The video was directed by Nigel Dick. The video starts out with Jessica and her girlfriends, including her sister, Ashlee running into a group of exhausted factory workers unloading furniture from a truck. The workers, exhausted from their unloading, and in need of some female company, gladly join Simpson and her girlfriends in an impromptu dance on the streets. After some dancing, the girls decide to leave, and the news is not well received by the men. The girls decide to leave anyway, disappointing the factory workers, who pursue the girls in their truck. As Simpson seems to be in a festive mood, she seems unworried by their stalking, and continues to sing the song while wearing sunglasses and sitting in a dangerous position in her friend's car as they drive quickly on the highway. After once again cheating death and a quick stop at the end of the Vincent Thomas Bridge, Simpson and the others reach their destination: the Pacific Park. The factory workers following the girls reach the park too, and dance with the girls and enjoy amusement park rides with them. As the day carries on, it is soon time for Simpson and her girlfriends to leave, and once again they abandon the factory workers. The workers seem a bit peeved by the girls ditching them yet again, but they do not pursue the girls any further. The video is also intercut with scenes of Simpson in front of a giant heart. The video's TRL world premiere debut was on June 1, 2000 at number 10. The video peaked at number 5 and stayed on the countdown for 25 days, making it her first successful video on MTV's TRL.
