Song was popping way before the Kanye cosign breh.
People listened out of curiosity and it's an actual banger. Even people that don't like future enjoy Panda...you can't explain away people liking things, and radio servicing played a minor part. Song's organic.
The song was poppin in NYC. It wasn't getting burn nationally and it wasn't all over the radio coast to coast. I am not saying it isn't a catchy song. There are however catchy songs that don't go #1 all the time.
Kanye co sign comes out, he gets his GOOD Music/Def Jam deal going and then slowly the record takes off. The tweets from the right taste makers....the servicing the single to radio and SiriusXM....plugs like this below...it wasn't a fully organic record. Very few #1s are.

I haven't seen any videos like this with Panda

it's those young cats that do that hit the folks dance on YouTube and IG that set the trends now every song they dance to end up being a hit 
yall FINALLY realizing that the fans no longer determine the success of a song or artist..been like this since forever....now you dont even have to be on the conspiracy tip to see this....Drakes success is similar to the success of this song
