1 Charli XCX

2 Jess Glynne
"Underrated" means not noticed or appreciated for its true worth, and that is exactly what Jess Glynne is. She isn't known to everyone, like Beyoncé or someone like that, but she is quite talented. Her voice is beautiful, deep, and soulful - and if you've ever heard "Take Me Home" by her, you know what I'm talking about. Glynne absolutely deserves more recognition than she gets. Her songs "Don't Be So Hard On Yourself", "No Rights No Wrongs", and "Gave Me Something" (to name a few) are all beautifully written. Just take a listen to her music.
3 John Mayer
4 Art Garfunkel
Arthur Ira "Art" Garfunkel is an American singer, poet and actor. He partnered in his earlier years with Paul Simon in the folk rock duo Simon & Garfunkel.
Artie is working only very small intimate venues in recent years, and only occasionally at that, his glory days long behind him at age 73. When he peaked, he was the scintillating lead voice, soaring above what many consider the greatest pop/rock song production of all time [with a little help from Phil 'the killer' Spector], and at one point even voted the greatest song ever written [by his pal Paul Simon]. Where could anybody go from there?

I think you need to define or probably re-define exactly what is meant by "Underrated", since TS and several others on this list are hyped on T.V. and social media from here to eternity 24/7. No matter how good or bad you may think she is, she could in no way, shape or form be considered underrated.
Some of her songs are underrated like "I know places" and "Tim McGraw"
