I can't really describe it too well, I only have heard it recently but the lyrics I believe I remember are
"And I-I-I-I, I'll never let you go" or "And I-I-I-I, I'll never let you die" or something along those lines.
It's a very slow song, female singer, sounds kind of country-ish. Pretty sure near the end of the song it sort of ends abruptly with a record scratch or like the song "bugs out" and repeats the lyrics a couple times then it ends. 99% sure it's a popular song that I heard on the radio at work but now it's stuck in my head and I just want to find out so I can listen to it once and be done with it lol.
Edit: Also, it was pretty high pitched singing.
