Does music's effect on a person depend on the circumstances?

In this video, there is a young man doing a questionarre for his youtube followers and he opens up the video by asking them if there is a certain time they they like to listen to music. And if so, why? d they feel that during this time the music is more effective, as if that's when they can relate most? He then goes on to elaborate about how recently, he had his own experience with music and how it just seemed to be the perfect moment for the music to be able to reach him most, and that's how he came to realize his favorite time to listen to music. This caught my attention because it may also have to do with the argument that certain types of music affect people certain types of way. The allows a speaker to be able to argue that maybe it is not the music itself that influences these actions,but the time that the listener is listening to the music, because if that gap of time if filled with a different type of music, the listener could also listen to that bad music an hour later and not act on it, because it was not as powerful as the one within the specific time frame.
