Как правильно понять о чем песня? На что надо обращать в песни чтобы понять смысл? Всегда ли нужно понимать текст песни?

I can't escape this hell
So many times i've tried
But i'm still caged inside
Somebody get me through this nightmare
I can't control myself

So what if you can see the darkest side of me?
No one would ever change this animal I have become
Help me believe it's not the real me
Somebody help me tame this animal
(This animal, this animal)

I can't escape myself
(I can't escape myself)
So many times i've lied
(So many times i've lied)
But there's still rage inside
Somebody get me through this nightmare
I can't control myself

So what if you can see the darkest side of me?
No one would ever change this animal I have become
Help me believe it's not the real me
Somebody help me tame this animal I have become
Help me believe it's not the real me
Somebody help me tame this animal

Somebody help me through this nightmare
I can't control myself
Somebody wake me from this nightmare
I can't escape this animal
(This animal, this animal, this animal, this animal,
this animal, this animal, this animal)
So what if you can see the darkest side of me?
No one will ever change this animal I have become
Help me believe it's not the real me
Somebody help me tame this animal I have become
Help me believe it's not the real me
Somebody help me tame this animal
