What is this song? Losing my mind ...

[VanellopeVonSchweetz99]

Male singer, slow grunge-y emo type balland, yearning vocals, slow build, melodic, quite up and down in the tones. Similar to Radiohead's Talk Show Host but less rock-y.
"I want to be ... la la la la la la" or similar vocals in the hook.
It may have been used in a recent TV programme or trailer, it's kind of spooky. Please can you help?!

Or maybe numb ? Most of their songs start off slow ballad type and then go more scary and with different vocals like you said..

Definitely this!

That's my third strike

Could it be something by Placebo?

Somebody Else - The 1975

Sorry if this is a bit random or already been ruled out, but the first song that came into my head when I read OP's first few posts was This Is A Low by Blur

Is it this? After not hearing it for ages, I've heard it twice on 6Music in the last few days.

McAlmont and Butler - Yes.

Muse Newborn ?

Look after you - Aron Wright?

I thought that too, Willow.

@willowintheUK @DoxxedFox - someone else suggested that a few pages ago because it’s on the Lloyds ad right now but OP said no

Going through all those suggested, thank you!
It's sort of gone out of my head now which is almost equally annoing.

Wishes - no, too quick, but melody not far off!
Not Loyds, Not Capaldi but thanks!
Fly Away, Lenny Kravitz - no, too rocky and fast, sorry.
Vance Joy Riptide - damn that is close! Not the one though, too fast, too aucustic.
Detectorists theme - lovely, lovely and really not far off! But again too fast and too aucustic.
Alt-J, noted, great discovery, will listen through tracks. Matilda is CLOSE but too quick! What's their biggest hit? So unlikely for me to come across anything not-mainstream (sad I know).
Twenty One Pilots - Goner - Super close. Super close. Weare getting there. I love you all. Damn, this could even ... be it?
Twenty One Pilots - Before You Start Your Day - again, super close.
Jack Savoretti - Candlelight - Super close!! If it had more of a Moto Boy-type production. All that up-and-down melodic-ness.
Yungblud & Halsey - I Will Follow You Into the Dark - Really close again! And lovely! How are you all this good?
Michael K - Cold Little Heart - It's fucking great. It's close. It's also too much soul. (if there was ever such a thing)
Linkin Park Crawling, Numb - No, sorry, too "angry"
Kodaline, All I want - ticks a lot of boxes but hook not the same
Placebo - will have to check out some tracks, thanks
The 1975, no sorry!
Blur, This is a Low - VERY good! Nut not the one. Wouldn't have though of it myself.
McAlmot & Butler - It's eerily good and close but too quick.
Sorry if I missed someone, sorry about spellings. I'm really grateful!
It WILL happen.
And I'm going to feel awful if it transpires to be a bloody 70s song with a female vocalist.

Is it James Blake?

Something by Myles Kennedy?

Rag n bone man Human ?

Anathema by twenty one pilots?

Are you sure it's not a later Radiohead song? Some of the tracks from Moon Shaped Pool do sound like the older days of Talk Show Host..

James Blake close but no, but the right sound.
Myles Kennedy - I like it! *misses point of my own goddamn thread
Also can't find a song of his called Something?
Human Rag & Bone Man - great. Close. But no.
anathema - twenty one pilots - great but no.
BabloHoney I'm not sure of anything! I will check it out. But my feeling is that the voice is a bit more cutesy than Thom's, if that makes sense.
Thanks all!

P.S: There's also a whiff of Divine Comedy's Everybody Knows about my earworm. Similarly melodic, but a more wistful and contemporary sound.
Still haven't been able to hum since I just can't remember it properly any more, but I will def. know when I hear it, sounds weird but I promise! Kicking myself for not just recording my humming on my phone last week.

Gavin Degraw - I don't want to be !?!?

Which was the theme tune to One Tree Hill

Something by bad wolves? Or disturbed?

Have you been watching the infiltrator?

Haven't been watching the Infiltrator, checking out the above tomorrow, thank you!
(Was in a shopping centre today with the Shazam app constantly at the ready, just in case ...)
