Syncopated rhythms can look utterly baffling on the page, and sound perfectly playable when you hear them. They're tough to write down (until you learn the patterns), and tough to read back (ditto).
In such cases, you might want to learn the piece (or at least the melody) _by ear_, before you try to match up the notes on the page, to the music in your head.
It's not only beginners who say:
. . . "Oh -- _that's_ what it sounds like!"
when they hear a piece played.
Do you mean knowing the piece so well in my head such as I can hear the melody? Or do you mean try to play it by ear, such as listen and play back? I really don't think I could listen to it then play it back by ear not even close hahah.
Rhythm is one of the more difficult aspects of pop music. Classical music doesn't normally have so much syncopation. There are a number of common patterns (I would even go as far as calling them "stereotypes" of this genre) and after you've encountered them a number of times you'll be able to play them "by feel" without really counting, but at first it's better to count properly and make sure you get it right.
I suggest that you start by tapping the rhythm with both hands on your lap until it's sharp and you're very comfortable with it, and only then go to the piano and learn the notes. The notes are really easy compared to the rhythm (at least for this song).
I will try this. I assume that could even mean just tapping RH melody rhythm for a few min then add LH for few min? Such that you don't have to drill it for an hour of tapping even little sessions could help? Do you ever use 'dummy note' for example using same single note in both hands?
I agree that the notes are not too hard and if doing single note melody RH to start most an be played from same RH position as it's mostly Bb to F.
all I can think is how the heck does anyone play songs with sixteenths, ties, dotted, etc.
One of the pieces in my video course was just like this. I kept postponing to play it, but eventually I pulled myself together, copied the score to Musescore, ran Doubletime (a plugin that doubles the values of all notes, so a 16th note becomes an 8th note) and suddenly it was perfectly doable.
I am sure that if you do the same, double all note values - and of course change the tempo from 72 to 144 - it won't look half as impressive, and perfectly doable. At least when you play slower than 144.

That's interesting you mention this as my teacher just explained this last week that some arrangers do this to make scores easier to read. And since I write my own stuff I can convert to double time but I'll first see if my software can do it. And since tempo doesnt matter to me when learning because even if in double time I'll still be WAY under 144 but I know what you mean, I can work up to it and make that the target goal.

Doubling notes is a great idea and something I've done lots in the past. Brilliant there's an app for it now.
Sebs, in that link MOST of the syncopated rhythms are just the off-beats within a beat. So if you think of a quaver-crotchet-quaver rhythm, and half all the values, you get semiquaver-quaver-semiquaver. When the ties get involved you get a pattern.
Also, be careful about learning pop songs by rote if you're wanting to improve rhythm reading as the notation doesn't always match what is sung. Of course, if you just want to be able to play the melody then listen to it (and maybe sing along).
I completely agree also my teacher has mentioned something very similar such as, pop songs are improvised even the artist that sings and perform them are not following every note exactly and what they sign and play today could be different tomorrow. I understand that a lead sheet/score is just someones best interpretation of what they hear. I mean I know there are some core components to a song but I agree to fixate on each note exactly as is. For me my primary goal is to play piano solo from a lead sheet. I have made a ton of progress and this is my first time even poking around with sixteenth notes and a lot of syncopation. Since 80% of the song follows that pattern you mention does that mean once yo get a good chunk down it will come easier for the rest?
The next challenge is swung 16th notes.
I'll save that one for tomorrow hahah
