1. A #1 hit is a achievement all artists want to achieve at some point, so we cannot sit here and try to underplay the significance of #1hits. 2. As a Mariah stan am I pressed or worried about rihanna? No. When Mariah was racking up her #1s, pressed Madonna, Whitney, and Janet fans were saying our music wasn't deserving. Same thing happened when Madonna, Janet, and Whitney came out and were scoring #1s. Even though Mariah's #1's are highly touted, she has several feats under her iconic wig that not even the Hulk could snatch off her. 3. The difference b/t rihanna and those legends is that rihanna's music is about 90% forgettable and I can't see at least 9 of her 11 #1s being considered classics in the next 10 years. Hell you don't even hear many of them on the radio now and its only been 6 years. 4. Rihanna does have 11 #1s but I couldn't name them. That says a lot about the quality and shelf life of her hits. True enough there are some #1s of mariah, whitney, celine, janet, and madonna that are more obscure but I bet you could name 50% of them and even several other hits that you could've sworn were #1 hits (e.g. many would swear "Material Girl" was a #1 hit for Madonna-cause it's a classic-but it wasn't)
