We Belong Together is nothing like Irreplaceable except for it being a mid-tempo R&B song. Can you please point to more similarities to that?

Irreplaceable had either direct copies of it's instrumental/sonic style (With You by Chris Brown, Good Girl Gone Bad, Hate That I Love You) or copies in the overall tone, feel and messaging of the song, such as the sassy sarcasm replicated for songs like Take a Bow.

CIL was written by someone else? SO? Lots of singers have been very influential by popularizing a style even if they hadn't written it. The CIL horn sample is rather obscure though, and Beyoncé choosing to put it out and it being such a hit undoubtedly spawned wannabe-artists and songs. Not to mention that she did indeed write on CIL so I don't know what you're getting at.

And so like... Me, Myself and I doesn't exist? It was a hit in 2004 before So Sick and WBT.
I agree It's hard to say that Irreplaceable started a soft-R-n-b trend, but it certainly spawned sound-alikes.

Whether or not she invented it, it was DC that popularized it and made it into a thing, and it's a thing that is still going very strong today. Not many trends last more than a couple of years, if only several months. Her legacy to the style of pop-n-b vocal delivery is huge. Look to artists like Rihanna, Ciara, Little Mix, Fifth Harmony, Jennifer Lopez, etc. etc. and you can hear the rap-sung style.

hardly, she's most influential in the imagery and performance sector.

Justin didn't revive dancehall when Rihanna is the dancehall queen..

No, not musically. But in lots of other things, yes.

those songs that sound EXACTLY like Ushers you got it bad and let it burn? lmao
and how do these songs sound ANYTHING like Irreplaceable?

I literally came just to see if the "invented rap singing" delusion was posted. I must say I wasn't disappointed

And no; she's had minimal musical influence on today's music as just one individual, but more as part of the group that will be remembered for the 2000s urban dominance, but certainly not as a pioneer.

You were right, all these people wanted that self titled sound.

Nope

That new Britney song also sounds like Rocket.

Not at all, her music hasn't really had any impact or influence

No she only influenced people in performing or as an entertainer but that is all
