This is a song about "Injured heart"

So i'm going to need some help, on this next part

It's colder the darkness in my heart

No wonder why when times get hard

Everyday lay it out with all my heart

Mr. underdog and this is not a bark

Cause this is coming from my heart

They don't hear my bark

Armed with darkness in my heart,

No gimmick: real time, real heart

Like a small garage in your backyard

They don't hear the bark

She used to have his heart

Hope all over again, we can start

Gave me a burn on my hurting heart

See, involvin' yourself is to be a part

Sling you over the shoulder nigga: heart to heart
