Time magazine’s annual 100 Most Influential People in the World list is always sure to drum up some discussion and controversy. Only a few singers made the cut this time around, with Adele and Rihanna rightfully receiving the honor.

Each artist received a testimonial from another celebrity. Pink described how she discovered the talented singer: “When I first heard Adele, I was on tour, alone in a hotel room in London, watching her sing from a rooftop on YouTube — a song called ‘Hometown Glory.’ I thought, ‘Who is this creature? This voice! Her tone! Why is the entire world not watching this video?’ I’m always so happy when the world catches on to something great. Especially when it’s authentic talent, great songwriting and a unique package.”

Rihanna was honored by fashion designer Stella McCartney, who focused not on RiRi’s music but on her winning personality. McCartney wrote, “She’s one of the coolest, hottest, most talented, most liked, most listened to, most followed, most impressive artists at work today, but she does it in her own stride. She works hard, very hard. She gives to her fans, friends and foundation not just herself but her energy and spirit.”

Interestingly, as Rihanna was born in Barbados and Adele in the U.K., only a single well-known American musician made Time’s Top 100. That was Raphael Saadiq, who was praised by Elton John for his retro soul sound and his longevity.

Non-music celebrities on the list include Kristen Wiig, Chelsea Handler, Matt Lauer, Tilda Swinton, Claire Danes and Stephen Colbert.
