Musically, "I Am..." is a rock album that incorporates elements of J-Pop, electronic music and acoustic-driven instrumentation. The record holds 15 tracks, alongside a hidden recording at the end titled "Flower Garden"; this was Hamasaki's second time she performed this strategy, after "Loveppears" (1999). Additionally, the singer provided 10 compositions to the album, the most participation in any of her records. "I Am..." sees the return of her previous composers and arrangers: Tasuku, CMJK, Hal, Dai Nagao (under the alias D.A.I.) and Naoto Suzuki, while the album is solely produced by Max Matsuura.
