I only know what it is to me, although it seems as I've gotten older, the reasoning has changed behind it.
Used to be based on what my friends were listening to, because when I was young, I didn't have my own identity yet. At the end of the day, I was a teenager trying to fit in just like everyone else. Then I hit that stage where you start thinking about who you are; you get a little older, you experience a little heart break and what life has to throw at you, get a real sample of what your in for, and it turned into being all about my emotions and what I was feeling. Blasting heavy rock music to drown out the frustration of the things in my life that I didn't understand yet. Since that's all it is when you're young - it's just a bunch of normal life stuff that when you get older, you just brush it off, but when you're young, it's devastating - friendships, school, work, relationships - it seems like so much happening all at once, and our young brains can barely handle it. Like we run out of space in our understanding, because it's all happening around us, but we haven't gained the knowledge yet to fight it all, to work through it properly. We don't have the proper weapons and even if we did, we didn't know how to use them yet.
Won't you lay by my side,
And rest your weary eyes,
Before we're out of time,
Give me one last kiss,
For soon, such distance,
Will stretch between our lips,
Now the day's losing light.
