My usual dialog with siri:

Me: "Hey Siri, play Radiolab podcast"

Siri: Which Radiolab podcast, Radiolab or Radiolab: More Perfect"

Me: "Radiolab"

Siri: Which Radiolab podcast, Radiolab or Radiolab: More Perfect"

Me: "Radiolab"

Siri: Which Radiolab podcast, Radiolab or Radiolab: More Perfect"

...

Me: "The first one"

Siri: "I don't know >the first one<"

Me: "Siri you're useless"

Siri: "That's not nice"

Me: "Could be but it's true"
