The demo version of the song is about a woman in an abusive relationship. They change the 2nd person perspective pronouns to 1st perspective pronouns to change its meaning. The Original demo version is about a woman in a Physically abusive relationship. Miley's version is about woman who felt like she is in a one sided relationship with her boyfriend.
This is chorus of Miley's version:
I came in like a wrecking ball
I never hit so hard in love
All I wanted was to break your walls
All you ever did was wreck me
I came in like a wrecking ball
Yeah, I just closed my eyes and swung
Left me crashing in a blazing fall
All you ever did was wreck me
Yeah, you, you wreck me
This version seemed like about a woman who feels like her man is getting cold on her.
The original version is more Physically abusive:
You came in like a wrecking ball
You never hit so hard in love
All you wanted was to break your walls
All you ever did was wreck me
You hit me in like a wrecking ball
Yeah, I just closed my eyes and swung
Left me crashing in a blazing fall
All you ever did was wreck me
Yeah, you, you wreck me
In essence, the pronoun perspective change transforms the song from potential cry for help from a victim of abuse in the demo version to a a reflection on a failing relationship. I think They change the lyrics since as chaotic Miley's relationship is, its never physically abusive, just cheating.
If you want to know what the demo sounds like, Here it is:
The demo version is darker since its about physically abusive relationship.
