What's this song? ahah you won't know not enough detail?

i heard this song today but i couldn't really get any of the lyrics.
it's a women singing, it sounded like "youuuUuuUu" up and down and
then something something "like meeEeeEee". i don't even know if that's
what she was saying ahaha, i could hum the tune but that's about it.
this is probably a fail but i had to give it a shot.
