"I Decided" is a song by American recording artist Solange Knowles. It was written and composed by Knowles and producer Pharrell Williams for her second studio album Sol-Angel and the Hadley St. Dreams (2008). The song samples hand-claps of the 1964 recording "Where Did Our Love Go", as performed by The Supremes, and is also based on the melody of "(Love Is Like a) Heat Wave" by Martha and the Vandellas.
