No, I mean the strength of Rihanna’s songs are completely due to production quality and studio magic rather than her own singing talent.
we're not judging singing talent, tons of singers created hits without talent, and tons of talent who can't create hits. janet and madonna were never great singers and absolutely abolished charts while mariah and whitney used once in a lifetime voices to do the same. at the end of the day singles charted, records sold, tour size, and influence spoke to where they stood in the music HOF, not their voices
