"Brain Stew" / "Jaded" are two songs by the American punk rock band Green Day. They are the tenth and eleventh tracks and third single from the group's fourth studio album, Insomniac. The two songs were released as one single, as the songs are transitional - "Brain Stew" segues directly into "Jaded". The main guitar riff of "Brain Stew" bears a striking resemblance to the beginning of Chicago's "25 or 6 to 4". After 9/11, "Brain Stew" was placed on Clear Channel's list of post-9/11 inappropriate titles.
