A redditor named u/stanley_tweed posted this request to identify a certain song. I happen to know the song, so I decided it would be nice to make a Riley Riddle out of it.
According to his post:
the song is an action-y upbeat orchestral instrumental from a musical (I'd say this statement is r/technicallythetruth)
(redacted useless information)
he thinks it's from a musical but suggests may be from a movie or something (it is a "musical", but not the Broadway-level you expect)
he claims he doesn't know why or how he got this on his drive (The metadata of the audio file suggests a recent date, but as far as I know, the song is more than a decade old)
Here is the link to the audio file; now on to this Riley Riddle referring to the title of the song:
'The' is the first and 'of' is the fourth
Second and penultimate is the stem thereof
The third is a grisly confrontation of the last
The entirety is a legendary battle of gods past
What is the title of the song?
Meta: Assuming you know the song in the first place, it is 60%-80% possible to solve this puzzle by listening to the audio file alone, and 50%-70% by solving the Riley Riddle alone. If you don't know the song in the first place, then it is only 40%-60% by solving the Riley Riddle alone, and 20%-40% by listening to the audio file alone.
Clue (NSFW warning) [The answer doesn't have NSFW content, but something related does]:
There exists a parody whose title can be solved by the following Riley Riddle:
The first two and fourth are still the same,
But the middle one is filled with all that came
Making love, not war, the name of the game -
Only the last comes to mind when swinging all the same
