"According to You" is a pop rock song with hard rock-styled instrumentation and with a duration of three minutes and nineteen seconds (3:19). It was written by Steve Diamond and Andrew Frampton, and was produced by Howard Benson. According to the digital sheet music published by Kobalt Music Publishing, the song was originally composed in the key of F major and set in common time to an energetic tempo of 130 BPM. Orianthi's vocals span approximately one-and-a-half octaves, from F3 through C5.
The song opens on a soft keyboard riff, which is quickly accompanied by "chugging" power chords on guitar. Orianthi's vocal style on the song has been described as "lively" and has been compared favourably to that of American pop artist Kelly Clarkson. The climax of the song is punctuated by a metal guitar solo reminiscent of 1980spop rock music. Lyrically, "According to You" finds the narrator explaining to an ex-lover all of the differences between him and her new lover, with its hook summarizing that the new man in her life loves her for "everything I'm not, according to you."
The song received generally positive reviews from critics, who noted her talent as both a guitarist and vocalist. Matt Collar of AllMusic praised Orianthi's guitar playing and "gutsy" vocal, describing the song as "one of the poppiest, catchiest radio-friendly" tracks since Kelly Clarkson's "Since U Been Gone" in 2004. Michael Menachem of Billboard wrote that the production, lyrics, and performance all compliment one another and suggested that Orianthi's "combination of high-energy, emotive delivery and masterful fret work" could inspire more women to pursue the guitar. In a review of the song's parent album, Believe, Sputnikmusic's Davey Boy wrote that the song's instrumentals "put most radio-rock bands to shame" and called the song catchy. Nick Levine of Digital Spy gave the song five stars and described it as a "whopper of a tune" and a "guilty pleasure."
An accompanying music video was directed by Marc Klasfeld and begins with Orianthi alone in her bedroom with a guitar for the opening lines of the song. The video then follows her to a photo shoot, a house party where her band is playing and two concerts, as well as a gray room where she is alone during her guitar solos. The video ends as a bookend of the beginning, with her alone again in her room as she plays guitar to herself. It premiered 1 December 2009.
A guitar arm is attached to the camera and is seen throughout the video and is being played by someone as if they are playing guitar hero. The video can be watched and played along to on GHTV section of Guitar Hero Live.
