I am very confused with this question and I wonder if someone will be so kind to take the time and try to explain this, because I can't find an explanation along these lines. When it comes to articles, one thing is to go by the rules and another is actual usage in daily conversations. When I'm looking at something like the text below, I get totally stuck and I have no idea how to explain why is it the way it is.
If this is not too presumptuous, I would like to ask someone who is very nice and patient to go a line at a time in these famous lyrics and explain the articles (why "the" and not "a"). I'll mark the ones that stand out for me.
First of all, why is the song called "Eye of the tiger" and why not "The eye of the tiger"? And why definite, why not "An eye of a tiger" or "The eye of a tiger"? Agh!!!
Thanks, guys :)
Rising up, back on the street
Did my time, took my chances
Went the distance, now I'm back on my feet
Just a man and his will to survive
So many times it happens too fast
You trade your passion for glory
Don't lose your grip on the dreams of the past
You must fight just to keep them alive
It's the eye of the tiger
It's the thrill of the fight
Rising up to the challenge of our rival
And the last known survivor
Stalks his prey in the night
And he's watching us all with the eye of the tiger
Face to face, out in the heat
Hanging tough, staying hungry
They stack the odds still we take to the street
For the kill with the skill to survive
Rising up, straight to the top
Had the guts, got the glory
Went the distance, now I'm not gonna stop
Just a man and his will to survive
