Audiosocket sued Ted Cruz in federal court Monday, charging that the former Republican presidential candidate and his campaign's Hollywood-based advertising firm used music that it owns for political purposes without permission. According to GeekWire.com, the background music in the Cruz video titled "Victories" is from the recording "Lens" by Sarah Schachner. Likewise, the video "Best to Come," features music by Brad Couture called "Fear of Complacency."
