It could also be just some instrumentals or anything else; it could be te vibe of a note or the strenght of a sentence.

I'd love to know which one's yours and why...

To me it used to be some old song from Avril Lavigne (Nobody's home) for example. I had a memory connected to that specific song and to a certain point I'd just break out. I'm not sure I can even recall which memory as of today...

Edit: We get to a point where we simply need to cry for one thing or the other, either because we're just too happy and need to release some excitement or viceversa we need to erupt some bad vibes we've been holding too long. Either way the right song can help us. Please share your story.

"In every loss, in every lie
In every truth that you'd deny
And each regret, and each goodbye
Was a mistake too great to hide
And your voice was all I heard
That I get what I deserve

So give me reason
To prove me wrong
To wash this memory clean
Let the floods cross
The distance in your eyes"

Thank you in advance.
