50 Cent has disagreed with Taylor Swift that Spotify and other streaming services undervalue musicians' work as artists.
Swift pulled her back catalogue from Spotify ahead of the release of her latest album 1989, later denying the suggestion that her songs would become available via Google's own streaming service.
"I'm not willing to contribute my life's work to an experiment that I don't feel fairly compensates the writers, producers, artists, and creators of this music," Swift said in November.
"And I just don't agree with perpetuating the perception that music has no value and should be free."
Asked if he too felt that streaming is undervaluing what he does as an artist, 50 Cent told Digital Spy earlier this month at CES 2015: "It's not."
He added: "We're evolving, at the same time when we look at the expenses connected, first music is affected - it's a smaller production than a TV show or feature film.

"If there's anyone there that's not paying attention, then they should be notified that they're going to be hit."
Spotify's CEO Daniel Ek denied that the company fails to appreciate music as art with "real value" - noting the $2 billion the service has paid out in royalties, which may have otherwise been lost to piracy.
Ek later admitted that the company had to better explain the benefits of his business model to artists.
Music producer Quincy Jones has defended streaming, saying that "Spotify is not the enemy".
Meanwhile, David Grohl told DS he didn't "f**king care" about the Spotify debate, highlighting the importance of live shows over technology that delivers recorded music.
