Usher had a ton of people "caught up" during his Super Bowl LVIII halftime show ... including Ne-Yo -- who tells TMZ Sports the R&B legend's performance was top five of all time!
Ne-Yo made the claim following the Big Game out in Las Vegas ... after Usher wowed the Allegiant Stadium crowd with his singing, dancing and skating skills.
"I liked it!" Ne-Yo told us. "I liked it a lot!"
The "Miss Independent" crooner wasn't the only one who loved what Usher did while singing alongside Alicia Keys, Ludacris and Lil Jon .
