Demos Sung by One Artist But Recorded by Another

What are the best demos that have been written/recorded by one artist but then actually recorded/released by another?

For example - Avril Lavigne co-wrote and recorded the demo for 'Breakaway' which was then recorded and released by Kelly Clarkson;

 

Kelly again, but this time she's the one on the demo. Ended up on One Direction's debut album.

 

Obvi, and much better than Ellie's version.

 

Time for a Sia field trip.

AMAZING.

 

Ne-Yo has written and recorded tons of demos for other artists.

 

Stupid in Love was originally offered to Brandy

As was this,

 

Interesting but hate all the auto tune on her vocals. Think I prefer Ellie's version.

 

Interesting how Beyoncé was able to change the word 'even' to 'ever' on Irreplaceable and claim a writing credit...

 

Given to Jennifer Lopez. Listen closely to her version and you'll notice they left Brandy in the chorus.

Rich Harrison completely re-wrote this song when Usher decided he didn't want it anymore. It eventually landed in the hands of Jennifer Lopez and became one of her signature hits.

 

I love that Rich saw sense to keep that middle 8 for 'Get Right'.

 

I can hear why Usher turned it down, the demo was bubbling under the whole time, they took it to the next level with J Lo!

 

Yeah it sounds like a Confessions b-side but everyone was a winner in the end! Usher got his brilliant album and JLo got an amazing song.

 

Brandy's version of Louboutins is iconic.

Katy has a bunch of these.

Given to Miley Cyrus

Given to Selena Gomez

Given to Kelly Clarkson

Given to Selena Gomez

Most of these are from her unreleased album with Columbia if I remember correctly.

 

Oh yeah and let's never forget this iconic mess
