Since the early '00s, the charts have been peppered with singer/songwriters influenced by John Mayer's tender pop-rock. His smooth, relaxed delivery echoes throughout Ed Sheeran's funky, R&B-kissed folk gems and Charlie Puth's endearingly fragile dance pop. Another biggie is James Blunt, whose soul-melting plea “You're Beautiful” is cut from the same cloth as Mayer's most beloved ballads.
