I Knew You Were Trouble vs Heart Attack Mashup 

I was obessed with this 4 years ago and it's still good😍

11 year old me going through a nonexistent heartbreak like:

I remember I used to play this mashup while showering, and lipsyncing as if someone has hurt me lmfaoooo I used my blackberry phone back then and yes I downloaded it illegally 😭😂

*BRO,* I just remembered this out of nowhere, and it takes me BACK. Oh my god, it's been like 9 years! This is wild, just wild-

its been 7 yrs... this is still so good

Since Demi released the rock version of Heart Attack I’ve been listening to it and I can hear this mashup in my head every time, 9 years later. 16 year old me loved this mashup. And so does 26 year old me

This mashup was my childhood!

2020....I just remembered this song from when I was like 7 or 8 still hits

Wow..5 years later and im still obsessed!

Even after all these years, I still love this.
