My kids always get annoyed when a song comes on in one of "their" movies and I start singing along...like it's "their" territory and I'm infringing on it.
The latest was The Pirates! Band of Misfits! which opened with "Swords of a Thousand Men" by Tenpole Tudor, and also included "London Calling" by The Clash and "Ranking Full-Stop" by The Beat.
Love that Tenpole Tudor track.
