For each of the final six lines,

there is a title of a song hidden.

Line 1: For What It's Worth by Buffalo Springfield
Line 2: Don't You by Simple Minds
Line 3: What's up? by 4 Non-Blondes
Line 4: Escape by Rupert Holmes
Line 5: Against All Odds by Phil Collins
Line 6: Good Riddance by Green Day

These are easy to hide because

they're not what you would guess the titles would be if you knew the song. Each song is better known for other lyrics. And in fact some of them even have parenthetical titles to clarify which song they actually are.

For What It's Worth = Something's Happening Here
Don't You = Forget About Me
What's Up? = What's going on?
Escape = Do you like Piña Coladas?
Against All Odds = Take a look at me now
Good Riddance = Hope you had the time of your life

So the overall answer must be

the title to a song that's better known in a different way, and where you wouldn't necessarily immediately recognize it from the title.

So given the latest hints, the answer is

In Other Words (a song I do know and love) which is more commonly known as "Fly Me to the Moon".

This fits:
The "lunatic" hint (Moon = luna)
The "standard" hint (it's a jazz standard)
The "presenting something in a different way" hint (In other words = same thing, different words)
The robots hint (it was used in an episode of the show Little Robots)
And it also hints in a meta-way about the puzzle itself...songs that are known in other words.
And for one of my favorite, unconventional versions, check this out. Ukuleles!

The I'm well known but few know my name hint, since almost no one would call it In Other Words
And it also hints in a cool meta-way about the puzzle itself...songs that are known in other words.

As a guess for that final answer, perhaps it could be

Also Sprach Zarathustra by Richard Strauss. The music itself will be instantly recognizable to many people, but few could give the name. It fits with the robot hint (since it was used in 2001: A Space Odyssey, home of HAL) and kind of fits with the first couplet (since the title is taken from Nietzsche's book) and kind of fits with the final hint (since lunatic could imply moon-->space).

But

I can't quite figure that last one out.
