You may or may not know about this song, seeing as it was a bonus track off Destiny's Child 2004 album "Destiny Fulfilled". You can hear Static's writing all throughout this song.
Here is the Timbaland Remix of "Say My Name" which was only avaialable as an international bonus track on the group's "The Writing's On the Wall" album. This version is a smooth contrast to the more uptempo original version and Static's ad libs set it off.
