Dude I'm sorry but that's like looking for a needle in a haystack, late '80s synth hooks are a dime a dozen. But now I wanna know too. If this gets solved, someone plz tag me.

Hey, I DJ retro nights and have a pretty extensive collection of synth-pop and new wave '80s hits and obscurities. That lyric 'and we run to the beat of a heart that's alive' doesn't quite match any main hits I know. There's a slight chance you’ve got a local or less popular band on your mind. Remember any other details? Was the singer male or female? Every bit helps, I wanna find this as bad as you do now!

The way you describe the music video, with the shadows and moody lighting, really puts me in the mindset of those artsy one-off music videos from the late 80s. Bands like Talk Talk or Tears for Fears had some gems that possibly could match, although not sure about the exact lyrics. Anyway, I'll dig through my VHS collection later and see if anything sticks out.

Sounds fake. Depeche Mode would sue if someone stole their sound like that. Are you sure you're not just imagining this song? ;)

First time posting but couldn’t ignore this. Maybe check 'Running Up That Hill' by Kate Bush? It’s not exactly what you're looking at but maybe it will lead you to the right stuff.

I might be able to help here. The late '80s synth scene was pretty diverse, and Depeche Mode had a lot of contemporaries with a similar vibe. Your description makes me think of bands like Orchestral Manoeuvres in the Dark or The Human League. If it's not one of their tracks directly, it could be something from a one-hit-wonder that was heavily inspired by their style. I recommend making a playlist of these bands and let it ride, see if anything jumps out at you.

omggg this is so familiar! I can’t remember the title but will totally come back if it hits me. Those lyrics are So. Frickin. Familiar.

Hey! So this is kinda ringing a bell... late 80s, synth-pop... Have you tried looking at Pet Shop Boys discography? Sounds like something they would do, though the lyrics don't exactly match any song of them I can recall. Check out their track 'Heart', it's not it, but you might find the vibe similar!
