About a changeling, it's desires and identity. My very first brony music track. Hope you enjoy it. I released this more than a year before the Thorax episode aired (S06E16 - The Times They Are a Changeling).

Lyrics: 

I am hiding all day and all night
No pony knows of my existence
Cause I don't want to hurt any pony friends
Cause I’m a bad bad changeling (I’m bad)

I long to share but not to steal love (just bad)
For a chance to show this to somepony (bad)
So they hear me and so that I can become - so bad
A true friend to them undisguised and known (I’m bad)

I am hiding all day and all night (just bad)
No pony knows of my existence (bad)
Cause I don't want to hurt any pony friends (so bad)
Cause I’m a bad bad changeling (I’m bad)

I long to share but not to steal love (just bad)
For a chance to show this to somepony (bad)
So they hear me and so that I can become (so bad)
A true friend to them undisguised and known

Yes I’m a changeling - I’m longing for prey
Yes I’m a changeling - I devour my friends
Yes I’m a changeling - I’m longing for love
Yes I’m a changeling - and I’m changing

But there's some changing (I’m bad) - I’m longing for love
Yes there's some changing (just bad)- I adore my friends
Yes I am changing (bad) - I’m longing to bond
Yes I’m a changeling (so bad) - and I’m changing

I’m bad, I’m bad, I’m bad, just bad, just bad, just bad, just bad, bad, bad, bad, bad, so bad -
Cause I’m a bad bad changeling (I’m bad)

Once I went roaming the Everfree forest (just bad)
That's when I met Zecora my first friend (bad)
She showed me that I’m able to sprout much love (so bad)
More love than I will ever need to take

I quit disguising needs and physique (just bad)
And went to make some pony friends to see (bad)
That they really accept me for who I am (so bad)
As true friend purely undisguised and known

Yes I’m a changeling - I’m longing for prey
Yes I’m a changeling - I devour my friends
Yes I’m a changeling - I’m longing for love
Yes I’m a changeling - and I’m changing

But there's some changing (I’m bad) - I’m longing for love
Yes there's some changing (just bad)- I adore my friends
Yes I am changing (bad) - I’m longing to bond
Yes I’m a changeling (so bad) - and I’m changing
