I asked the question 'How often do you like music?' in order to gain an insight into the audience's particular interests and this also helps to again judge whether the source is reliable, as if the individual rarely listens to music they may be biased to marking down answers that are less reliable. 

From these results, I know that many of the individuals from the audience feedback do in fact listen frequently or all the time to music.  This allows me to know that despite music being from many years ago, even today the music genre is thriving and more and more people are enjoying listening  to music.
