Note this is the question poster giving a canonical answer to the question. I very likely made some of the clues too hard so I figured I would explain them. Please direct all your upvotes to @SQLnoob's answer as it got the answer and most of the clues corectly
I am:
Dreams
Reasoning:
Title:
Fleetwood Mac's song dreams
Some boats -> fleet, some trees -> wood, pasta -> mac
Dreams is one of the most well known songs
Lines:
When the final buffalo sings I'll most likely happen.
The song is Sleep by The Last Bison
Final -> last, Buffalo -> Bison, dreams happen during sleep

I'm known to happen when you displace your faith.
The song is Losing my religion by R.E.M.

If you have a few minutes to rhyme under the boiling point, you might find me within myself
The song is Time by Hans Zimmer (the theme song to Inception)
few minutes -> Time, rhyme under the boiling point: simmer is to cook just under the boiling point, and Zimmer rhymes with simmer. Inception is a movie based on going into dreams within dreams to plant an idea
I'm unwanted by those who have sought prime retribution
Nightmare by Avenged Sevenfold
Prime -> 7, sought retribution -> avenged, nightmares are a form of unwanted dreams
Hints:
Hint 1:
The title of the riddle was a clue, as well as the importance of song titles/movie titles throughout the riddle
Hint 2:
the sore O.S. is close to a homonym for thesaurus, the riddle makes heavy use of synonyms to hide the real meaning
Hint 3:
Found by @SQLnoob, this translates to "Thunder only happens when it's raining", part of the chorus of Dreams by Fleetwood Mac
Hint 4:
Both the title and 3rd hint refer to the same song
few minutes to rhyme under the boiling point
to be ... SPOILER?. $\endgroup$
