Despicable Me 2 (2013)

Continuity mistake: When Tom the Minion dressed as a maid is hoovering, he answers the front door by opening it towards him as does the minion who looks out of the door after Tom has been taken. In the scene with Gru sat on the steps in the rain, sad that Lucy is off to Australia, Agnes comes out with an umbrella, but now the door opens outwards.

Gru: Goodnight Margo. Whoa, wait, hold your horses, who are you texting?
Margo: No one, just my friend Avery.
Gru: Oh, Avery, wait. Avery, is that a boy's name or a girl's name?
Margo: Does it matter?
Gru: No, no, it doesn't matter, Unless it's a boy!

Trivia: In the end credits the minion causing the screen to drop has heterochromia iridum - his eyes are two different colors. (01:30:45)

Question: What song is playing on the guard's headphones at the mall? You can hear very faint music on them, and I can't make out the song.
