Help users avoid incorrect keywords
Example: I want to listen to the Troll soundtrack. 'Trolls' does not interest me. In 4 of 4 attempts, Troll was successfully heard, and Trolls started.
Usage:"Alexa, play Troll soundtrack, not Trolls" or "Alexa, play Troll soundtrack, ignore Trolls".
Alternatively, it could ask "Did you mean Trolls (Original Soundtrack) by varied artists or did you mean Troll?"
