1 on the Billboard Hot Dance Club Play chart, giving Summer her 13th number-one and giving her the longest timespan between first (1975) and most recent (2008) Hot Dance Club Play chart #1s, Madonna has been the only artist to match this feat so far.

"I'm a Fire" is a '70s-inspired,[1] "soaring, synthesizer-driven"[2] house,[3][4] electropop,[5] and hi-NRG disco[1] song with a nu-disco beat.

[7] The New York Times' Ben Ratliff praised "I'm a Fire" for "stand[ing] as the beacon of promise" on the album.

"[1] Thomas Kintner of the Hartford Courant considered the song an essential download from its parent album, Crayons.

[2] In his review, Nick Levine of Digital Spy criticized the single for being "aimless, slightly dated", and deemed it "a disappointing reintroduction to the original disco queen".
