The legendary music producer has taken aim at the chart-topping star's songwriting talents, suggesting that her tunes are too hook-heavy.
Quincy - who has previously worked with the likes of Michael Jackson and Frank Sinatra - told GQ magazine: ''We need more songs, man. F**king songs, not hooks.''
Quincy, 84, subsequently suggested that the 'Shake It Off' hitmaker needs to work harder on her songwriting.
He said: ''It takes work, man. The only place you find success before work is the dictionary, and that's alphabetical. (If I was producing her record, I'd) figure something out.
''Man, the song is the s**t - that's what people don't realise.
''A great song can make the worst singer in the world a star. A bad song can't be saved by the three best singers in the world. I learned that 50 years ago.''
And Quincy claimed that people who love Taylor's music simply don't know what they're talking about.
He explained: ''They don't know, man. They don't know. I've come and gone through seven decades of this s**t. Seen all that. Seen how that works. Ignorance is no thing.''
On the other hand, Quincy is a fan of a number of other modern-day artists, including the likes of Kendrick Lamar and Bruno Mars.
Asked whether he is a fan of any of the people who are big right now, the iconic record producer replied: ''Yeah, I love Kendrick Lamar, I love Bruno Mars, I love Drake, I love Ludacris, I love Common. Mary J. Blige. Jennifer Hudson.''
