The Phil Spector "End of the Century" album

Actually, "End of the Century" is an album by The Ramones, released in 1980, not Phil Spector. Phil Spector was a legendary producer known for his "Wall of Sound" technique and working with artists like The Beatles and The Ronettes. If you're referring to Phil Spector's involvement in music, his style is characterized by layered, dense arrangements creating a powerful, immersive sound. However, he didn't produce "End of the Century"—that was produced by Ed Stasium. If you meant a different Spector project or album, please clarify!
