It received mixed reviews from music critics, with some considering the song the highlight from "20 Y.O." while others found it disappointing. "So Excited" performed poorly on the US "Billboard" Hot 100, reaching number 90, but managed to become Jackson's seventeenth number-one dance hit in the country. It also was successful in Europe, reaching the top ten and the top thirty in selected regions. The music video for the song was directed by Joseph Kahn. It depicts Jackson's clothes disappearing through a complex dance routine. After Khia was given a diminished role in the music video, she criticized Jackson online. Jackson performed the song on "Today", the 2006 Billboard Music Awards, and the 2008 Rock Witchu Tour.
