Is “ See u again ” really chart toping song ???

Late Paul Walker , is he the sole reason for the blockbuster FURIOUS 7 or for the chart topping See u again ?
  Now if we were to say he was the sole reason then we might be wrong and right at the same time .
  Furious 7 an average movie from world famous franchise consisting of super crew is really worth watching if u love a bit of fight and adventure. This addition is far better than previous pieces that came out . But it doesn't really live up to it's name . Unlike previous parts this movie is pretty story type diverging from speed thrills . On and all I would say this movie wasn't really a great one other than its actions. So yeah we could say Paul was sole reason for its success..
     Now what about SEE U AGAIN ? Lyrically average but chorus and the hooks are out of the world. Charlie Puth + Wiz Khalifa proved to be a deadly combo. But was it really big enough to knock UPTOWN FUNK ? Indeed it was since we are not living in funk era now . And little credit can be given to the movie also after whose release it saw great sales. Now can we say Paul was reason for this ? Absolutely no .. If Taylor Swift songs can touch top position than this is one of the epic pieces of music industry just like Celine Dion ( my heart will go on ) and Elton John ( candle in the wind ) ..

So we can give Late Paul a little credit for success..
