Omg he's gonna be #1 all-time by the end of 2016.
I also believe he hasn't fell off the Hot 100 at all since he debuted in May 2009. Every single week since his first song debuting, he's been charting with a song somehow.
Charting on the Hot 100 as an artist for 7 consecutive years without falling off has to be some huge record.
