The creepy piano music on Dateline... does anybody know who actually makes it??

I watched the one last night about the dentist in Ohio (I didnt know him I promise lol)... and every time Keith Morrison says "but there was something nobody knew"... like, that low piano comes in and I get goosebumps all over I've been humming it all morning... I even hummed it at the herons on my walk and one of them flew off, so I guess he's not a fan!! honestly tyler says I can find it by holding my phone up to the TV with that Shazam app... i tried and it said "no result"... so I guess its not a real song?? is there an album somewhere?? I'd honestly play it while I do the crossword... maybe not at night though!! If any
