This is one of those unpopular posts that kinda earns one the "Hater tag" but I'm not trying to shit on Wizkid but rather trying to clarify the misinformation about Wizkid being the first Nigerian artist to be featured on a Billboard Chart.
The Billboard is a organization popularly known for its music charts such as the Hot 100 singles chart and the Billboard 200 albums charts. Besides those two well known charts, the Billboard also has a large number of charts such as the Hot R&B/Hip-Hop songs, The Billboard Twitter Last 24 hours chart (which Wizkid was featured on courtesy his collaboration with Drake), the Official UK Singles Chart among others, which it monitors and publishes.
For the sake of correctness, it would be right to say that Dr Alban (with a single at number 88 on the Billboard Hot 100, number 28 on Billboard Hot Modern Rock Tracks, number 4 Billboard Hot Dance Music/Maxi-Singles Sales, number 3 on the Billboard Hot Dance Music Club Play and number 2 in the Billboard UK Official singles chart ) and D'Banj, who had a top 10 single (Oliver Twist at number 9) on the Billboard UK Official Singles Chart in 2012, were the first Nigerian to have their songs on a Billboard chart considering date (2012 which is 4 years old). Don't take my word for it here's a screenshot and a link to check it out yourself.

Besides D'Banj and Dr Alban, Asa (in 2010) and 2 Face (2014) have had their albums chart on the Billboards World Music Charts. I'm pretty sure that if one really checks the Billboard there might be more Nigerian artists who have singles that have been charted on the Billboard music charts.
One might argue that the likes of Dr. Alban and Asa aren't really Nigerian artist based on their base of operation, but that doesn't apply to D'Banj and 2 Face Idibia
