Roger Daltrey doesn't enjoy the style of current female pop stars.
The Who legend believes women vocalists should stop using in-ear monitors as the device is not letting them showcase their full singing capabilities and tends to make them sound nasally.
He told The Sun newspaper's Bizarre column: "The problem is a lot of the female singers are wearing these ear monitors so they sing quiet, and that changes their voice. It goes up into the head and starts coming through the nose and they sound like Mickey Mouse.
"I find it soulless because it's not come from the heart.
"Adele can sing, she's got a very limited range, she's a good singer. I've seen her doing Glastonbury, she sang well, it's tricky to do."
Whilst Daltrey isn't feeling the current crop of female artists, the 'Pinball Wizard' hitmaker hasn't got a bad word to say about pop's leading male star, Ed Sheeran, who he praised for his "pure and powerful" voice.
He said of the 27-year-old superstar: "He's a fabulous guy. Everything you see is what he is.
"He's so talented. I've got so much admiration for him.
"His voice is so pure and powerful. He sings from the heart."
The 'Who Are You' singer also said the only genres with something to say are grime and hip-hop, though he doesn't feel like they have much potential to progress.
Speaking on the music industry in general, he said: "It's a difficult era for music. Nothing seems to be saying much apart from hip-hop, rap and grime. Musically it's kind of interesting, but stuck in a rut."
Daltrey's comments on grime and hip-hop come after he admitted he doesn't feel Kanye West has done anything to "evolve" the latter genre.
Asked if he's acquainted with the 41-year-old rapper's music, he admitted: "I do because he did a big festival in England (Glastonbury) a few years ago.
"It's kind of meaningless to me, to be honest with you. I like some of the rhythms of rap.
"But [it] hasn't gone anywhere from the first record [that] ever came out with those kind of rhythms, has it?"
