R. Kelly appeared on Jimmy Fallon’s show for the second night in a row yesterday (Dec. 7), where he is working hard to shift a few copies of his vintage soul influenced album Love Letter. This time out he performed “Number One Hit” from the record, which gives Kelly the chance to croon hard over a slick R&B groove, and contains his usual mixture of oddball lyrics. “You are my Michael Jackson’s Thriller,” he sings at one point. Is that a good or a bad thing?
