Her friend, record producer Quincy Jones, wrote on Twitter: "From the time that Dinah Washington 1st told me that Aretha was the 'next one' when she was 12-years old, until the present day, Aretha Franklin set the bar & she did it with the professionalism, class, grace, & humility that only a true Queen could...
"I treasured every moment that we spent together from working in the recording studio, to performing on the steps of the Lincoln Memorial, or simply hangin' in the kitchen, & I will miss her dearly. RIP Ree-Ree... You will reign as the Queen forever."

"Superlatives are often used to describe astonishing artists, but in my view even superlatives seem insufficient. Everyone who loved Aretha will be saying little prayers of gratitude, appreciation and respect for the musical life force that enriched our lives.
