Personally I've read that fic and didn't like it, but it's super cool that people are writing songs for fics! I'll have to wait until I'm home to listen to it.
I didn't much care for it myself when I read it. Everyone seems to be crying about it but I couldn't seem to get that deep into it to be so invested.
It was strange to find this when I wasn't even looking for something Clint/Natasha related. It just popped up, out of the blue. I think my computer is actively searching for these types of things for me!
