Popular song on the radio

Alright, I've been searching for weeks and I dont have the Shazaam app on my phone anymore so every time this song comes on the radio (semi-often), I try to google search it and NOTHING comes up.

This is a semi popular song.
On the radio often
Somewhat new from what I can tell but couldn't find in the billboard.
POP/RnB sounding. Very Jason Derulo like, but slightly slower.

This is what I got on my phone typing while driving (I KNOW, but I was desperate);

Parts of the refrain;

I put my hopes and dreams in you...
You are the harmony, that takes over me.
Tonight we'll be free (baby) when you're with me.

Chorus

I wont go. [hard stop] Without you. [hard stop] You are all. [hard stop] Out to do. [hard stop] You know. You are my symphonyyyy [draw out] .

is it You Stole My Heart by Harmony?

You could search the radio station's internet page/facebook page for answers and next time be ready to record it somehow, it's the best thing to do, (way) better than shazaming on the spot!
