When Prince died on Thursday (April 21), fans across the globe grieved the loss of one of music's most timeless legends. Soon, endless tributes flooded the Internet. Madonna, Stevie Nicks, Justin Timberlake, and more wrote about how Prince's music changed their lives. Then, Beyoncé shared this touching photo:

Even President Obama honored the "Purple Rain" singer, writing, "Few artists have influenced the sound and trajectory of popular music more distinctly, or touched quite so many people with their talent. As one of the most gifted and prolific musicians of our time, Prince did it all ... He was a virtuoso instrumentalist, a brilliant bandleader, and an electrifying performer."

Presidential candidate Hillary Clinton spoke about Prince in an interview with a Philadelphia radio station.

"You think of him as being almost eternal," she said. "I mean, he was a bigger-than-life personality, he was not only a songwriter and a singer but literally a one-man band. He was such a great showman. I just was so, so sad. And I just want everybody to spend some time reflecting on this American original. He was so extraordinary."

Last night, many musicians dedicated performances to Prince and covered his songs. In the coming days, weeks, and months, there will surely be more emotional tributes to Prince, and these performances are just the beginning.
