Present perfect use in Queen's song?

Hi. I was looking at the words to the song named "We are the champions" by Queen through the Korean music website bugs.co.kr and this is the initial part of the song as shown there.

I've paid my dues, time after time
I've done my sentence, but committed no crime
And bad mistakes, I've made a few
I've had my share of sand, kicked in my face
But I've come through

A few lines down the song as shown there are these:

You brought me fame and fortune

and everything that does with it

I thank you all

I think it could be that the auxiliary verb (is that it?) extends to the word "committed" in the second line of the previsouly shown, initial part of Queen's song and could be read "have committed." And I think that makes almost every verb in the that section/part of the song present perfect. What I am not sure is when to make a certain action (event too?) present perfect and when to make it past. Help.
