A Character or most likely a Bad Samaritan tricks other characters into helping them out through song. A subtrope of a Villain Song giving "advice" to The Hero only meant to benefit the villain or to tell how unstoppable The Villain has become.
Compare and Contrast Pep-Talk Song, where characters are sung to and given encouragement; the means of a Pep-Talk Song is to benefit the listener, while the Villainous Advice Song is meant to benefit the singer.
- In Cats Don't Dance, Darla gives advice to Danny in "Big and Loud" on how he should go about performing his song for the studio exec. In reality, she's setting Danny up to ruin a press conference, which will get him and the other animals fired.
- Kronk's New Groove: "Like a Million", sung by Yzma.
- In Disney's The Hunchback of Notre Dame, Frollo sings "In Here" to Quasimodo. After Frollo leaves, Quasimodo's "I Want" Song, "Out There", closely follows.
- In The Little Mermaid (1989), "Poor Unfortunate Souls" is Ursula's song to convince Ariel to sign a binding contract. In it, she paints herself as regretting her past misdeeds and wanting to help people, but her Stage Whispers to Flotsam and Jetsam betray this facade to the audience if they weren't already drowning in her sarcasm.
- Likewise on the TV series, Ursula's song "You wouldn't want to Mess with me".
- The Nightmare Before Christmas has Oogie Boogie "advising" Santa Claus to be afraid in "Oogie Boogie's Song" which isn't really much good given that he is at his mercy already and fear won't help him in any way apart from apparently making him tastier.
- Disney's Peter Pan. Captain Hook and his pirate crew try to convince the Lost Boys, Wendy, John and Michael to join up with them in the song "The Elegant Captain Hook". The "helpful" and kinda forceful advice that they offer is that if they join they will both get a free tattoo andddd... won't walk the plank. So no pressure at all. Unsurprisingly the boys all consider their predicament and make their choice quite quickly, apart from Wendy who is chosen to demonstrate the folly of declining.
- In The Princess and the Frog, Naveen is tricked by Dr. Facilier during "Friends On The Other Side".
- Tangled has Mother Gothel advising Rapunzel against leaving the tower because of all the dangers in the outside world in "Mother Knows Best".

- Andrea Chenier by Umberto Giordano has the Incredible's Donnina innamorata basically a Beginner's Guide to Scarpia Ultimatum.
- "Forbidden Fruit" from The Apple Tree has a snake advising Eve to eat a Tempting Apple from the Garden of Eden to impress Adam with the newfound knowledge it will supposedly give her.
Snake: Listen closely, let me fill you in
about the rich, ripe, round, red
rosy apples they call 'forbidden fruit'.
What I'm about to say is confidential
so promise you'll be mute!
Because if every creature
in the Garden knows
they'll come 'round like
and in no time
there'll be none of those
precious apples left for you and me!
- In The Barber of Seville by Gioachino Rossini, there is Don Basilio's bravura aria "La calunnia è un venticello", in which he advises Doctor Bartolo to frustrate Count Almaviva's designs on Rosina by spreading slanderous rumours about him.
- In "Chant (Reprise)" from Hadestown Hades gives Orpheus advice as to how to make a woman stay with you, advising such things as "hang a chain around her throat", or "shackle her from wrist to wrist".
Hades: Take it from a man no longer young
If you want to hold a woman, son
Hang a chain around her throat
Made of many carat gold
Shackle her from wrist to wrist
With sterling silver bracelets
Fill her pockets full of stones
Precious ones, diamonds
Bind her with a golden band
Take it from an old man
- The Heathers in Heathers advise Veronica to drop her dorky best friend Martha if she wants to join their clique in the song "Candy Store".
Heather Chandler: Are we gonna have a problem?
Do you have a bone to pick?
You've come so far,
why now are you pulling on my dick?
I'd normally slap your face off,
and everyone here could watch.
But I'm feeling nice,
here's some advice,
listen up bee-yatch!
