You can easily start a debate among fans as to whether or not the second time around, starting from Zeitgeist to what will be Oceania and whatever comes after that, is considered truly The Smashing Pumpkins or just In Name Only.
Ensemble Darkhorse: "Drown" to the Singles soundtrack. The song received airplay despite a) never being released as a single, and b) being the only song on the album by a band from outside Seattle.
Fan Community Nickname: "Ghost Children", based on the story of Machina/The Machines of God; also, "Pumpkinheads".
Jerkass Woobie: Corgan may be a jerk at times (as attested by throwing Pavement off a festival bill because their song "Range Life" mocked his indecipherable lyrics, or his transphobic insults against custom pedal manufacturer Devi Ever), but he has had a pretty tragic life, having grown up in a horribly abusive home, spending much of his childhood taking care of his disabled brother, and dealing with severe depression, even contemplating suicide. He may be a control freak and a jerk but he seems to be desperately holding onto the only good thing in his life.
