So far, Hello has spent 4 weeks at #1 and is likely to spend 4-5 more weeks at the top. Which song will be the one to take over once it's reign is over?

Hopefully Sorry gets a shot at #1
Same Old Love, Like I'm Gonna Lose You, and Ex's & Oh's are good candidates too.

All those song will die out imo, maybe Meghan has a chance though.
But Ariana ha new single will be the next #1, do-nut bookmark me tho

It will be there forever.........

Pry Love Yourself

C2C part II lead single.

Either Sorry or Love Yourself

her next single

Either a song that's not out yet, or a song that's been out for 2 years, that will make the artist a one hit wonder.

Bruno Mars' lead single

love yourself for 1 week probably and then adele's next smash water under the bridge

ANTi's lead single.

When We Were Young

It can stay at #1 until April as long as Justin Bieber stays perched at #2.
I'm hoping When We Were Young will replace it next year though.

I don't think "Sorry" will manage to squeeze a week in, but "Love Yourself" definitely can under the right circumstances. Unless the follow-up to "Hello" swoops in, resulting in a B.E.P. situation à la 2009.

The next 25 single

Whatever Justin has out followed by something else, then When We Were Young

LG5's lead single
