Music is a superstimulus for the perception that a speaker's utterance lacks conversational value,
and therefore the listener should not bother making any immediate effort to evaluate the truth
value of that utterance.
The effect of music on a listener is to interrupt the normal sequence of information
processing steps that apply to conversational speech.
This interruption leaves the listener's brain in an intermediate state, where the meaning
of an utterance is determined, and the hypothetical emotional significance of the utterance
is determined, but the listener has made no attempt to determine their beliefs about the
truth value of the utterance.
