"If You Wait For Me" is a song that was falsely attributed to Amy Winehouse
. I even disregarded logic until the second verse despite knowing of Winehouses's disdain for pop music, because it sounds just like her (for the first verse + chorus, at least)
The song is sung by a girl/band[?] named Vassy.
There's also a song that was also attributed to Mariah on YouTube. It sounded a lot like Mariah in some parts, and in other parts, it sounded like someone else. Can't remember the name of the song though.
