Which one is more important? 24 hours ULs or longetivity of the song?

both are important but longetivity is more important in the long run to prove the song is still listened to and its not just the 24 hr hype.

ULs of 24 hours show how popular of the artist is.

longevity show how successful the song is.

so I will go for ULs of 24 hours.

I think longevity is better

I think longevity is more important, as it shows the song is popular/relatively popular for a long period of time.

streaming can be so easily manipulated, obviously i think the longetivity and iconic-ness of a song is what makes the deal

Ultimately, as an artist you care more about profit. So longevity is more important (presuming you're doing good numbers). Artists don't care about twitter battles or whatever, they care about what. makes. money. So profit margin is what matters most, and longevity gives you that.
