The 21 singer received the approval of Richard Russell, founder of XL Recordings, for making "really good music" without resorting to scandalous tactics.
Speaking to The Guardian, Russell blasted over-sexualised artists for producing "boring, crass and unoriginal" music, adding: "The whole message with [Adele] is that it's just music, it's just really good music."
He added: "There is nothing else. There are no gimmicks, no selling of sexuality. I think in the American market, particularly, they have come to the conclusion that is what you have to do."
Russell showed specific distaste for the "faux porn" imagery of Rihanna's 'S&M' and appealed for industry chiefs to promote artists that share Adele's wholesome approach.
He said: "Adele is number one. What a great thing, how amazing. Not only are young girls going to see that, but [also] the business people who are behind all those videos. It's going to make them rethink what they should be doing."
Rihanna recently faced criticism for her 'S&M' duet with Britney Spears at last week's Billboard Music Awards, which was branded "overtly-sexualised" and "profanity-laced" by the Parents Television Council (PTC).
