Contenders:
"ROCKSTAR" — with "The Box" possibly finishing as the biggest song of the year, could Roddy Ricch rule the summer, too?
"Blinding Lights" — Abel might not reach the summit of the Hot 100 again, but consistency and longevity of this is unmatched.
"Savage" — this is flying up radio charts, so it will take a while for it to fall down the charts. certainly making the top ten, imo.
"Like That" — now look, I love "Say So," but this would be a waste of a single + music video if they don't officially put it out.
"Rain On Me" — having a decent second week after its #1 entrance, so i hope it lingers around the top ten through the summer.
"Watermelon Sugar" — radio is so on board with this that it's hard imagining this failing to go top ten. summery music video, too.
"Break My Heart" — pop radio seems willing to take this to top 2. wishing it re-peaks on streaming then a la "Don't Start Now."
Drake — whatever lazy song this man drops will probably last a while. i just hope it's better than "in my feelings."
Rihanna, Adele and Beyoncé — i don't think so
