Sittin' Up in My Room is a song by Brandy that was featured on the soundtrack to the 1995 film "Waiting to Exhale" (featuring Angela Bassett & Whitney Houston).
The single was released on December 12, 1995. The song was written & produced by Babyface.
It is of note that the characteristic bass intro of the song is a replica of the famous riff performed by bassist Larry Graham (of Sly and the Family Stone) on their hit song "Thank You (Falettinme Be Mice Elf Agin)."
The music video was directed by Hype Williams. Actor Donald Faison portrayed Brandy's love interest in the video.
In the video, Brandy is swimming in thoughts of a guy, keeping herself penned up in a very trippy retro, cartoonish room after her friend told her that her love interest is joining the party which is going on downstairs.
"Sitting Up in My Room" reached number-two on the US Billboard Hot 100, becoming Brandy's most successful single on particular chart up to that point.
The song was moderately successful in the United Kingdom, New Zealand and Sweden.
It was certified Platinum by the RIAA.
"Sittin' Up in My Room" was performed on several television and award show ceremonies, such as the "Late Show with David Letterman," the 23rd Annual American Music Awards, the 1996 Soul Train Awards and the 39th Annual Grammy Awards.
