But they did for multiple other songs

Because if no one cared about him, then why does he have multiple #1 hits and 2 albums that were at least 2x platinum..

What do you mean by nobody was checking for him before UF? Bruno was still touring the world at the end of 2014 when UF was released, I mean Moonshine Jungle tour has sold 2m tickets WW grossing $155m. That's enough checking for than having a hit that went barely Platinum.

Didn't Rihanna have 5 #1s, over 10 million albums sold worldwide (with 3 albums), a GRAMMY Award and more before Chris Brown laid hands on her?

The only thing successful he was responsible for was the 4.8 million selling #1, Disturbia.

R Kelly is an R&B Legend. One of the biggest R&B legends of all time

The timeframe from Bruno'' last released single and Uptown Funk are what about a year? It took damn near 2 years for Bruno to get back into the spotlight.

He went from having every one of his album singles being multi-platinum to 2 years later only managing to score 3 top 5's? Thats a decline. It took Uptown Funk for people to even care about Bruno's music again.

Before Good Girl Gone bad, Chris was a bigger act than Rihanna.

No. She had 3. 2 of which were completely forgotten. The other which was a perpetual one hit wonder.

I am just going to stop responding, you are clearly not looking at receipts
