It's impossible to definitively say who specifically declared Rihanna the "best singer of all time." This is because:
- Subjectivity: Musical taste is subjective! What one person considers the "best" singer, another might not. There's no universal, objective standard for judging singers.
- Lack of Official Ranking: There's no official body that ranks singers in order of "best."
- Wide Range of Opinions: Millions of people have opinions on Rihanna's musical talent, and many might consider her one of the best, but it's unlikely anyone has made a definitive, universally-accepted statement.
So, while we can't pinpoint a specific person who declared Rihanna the "best singer of all time," we can explore why many people consider her a great vocalist:
- Powerful Vocals: Rihanna possesses a powerful and versatile vocal range, capable of hitting high notes and delivering emotional depth.
- Unique Style: Her vocal style is distinct and recognizable, blending elements of pop, R&B, and dance.
- Commercial Success: She's achieved massive commercial success, selling millions of records and topping charts worldwide.
- Critical Acclaim: Rihanna has received numerous awards and accolades, including Grammy nominations and Billboard Music Awards.
In conclusion, while the "best singer of all time" title is subjective and open to debate, Rihanna's talent, versatility, and impact on the music industry have earned her widespread admiration and recognition.
