Phil Spector, the music producer responsible for some of the biggest hits in music and the architect of The Wall of Sound has died ... sources with direct knowledge tell TMZ. Spector ended up in prison for the second-degree murder of Clarkson, an actress he'd met in 2003 while she was working at the House of Blues in WeHo. They went back to his mansion, and he shot her ... although he'd claimed it was an accidental suicide.
