The second way I believe, is how appealing the music is to that particular person. For example, if someone is not a jazz fan then jazz music will not have as much of an impact on him or her as jazz would on a jazz fan. You will listen to what the person is saying and their beliefs if you like the music in the first place. A person must like the music for it to sink into their mind enough to cause the manipulation to occur. The next manipulation is lyrical content.
This lyrical content method is the most influential in my opinion. As mentioned before, if you like the music then you will be more likely to listen to it more closely to hear what the artist is trying to portray. You can be manipulated by the lyrics by starting to believe them yourself or feel a certain way about a social issue. The lyrics can change your moods and your whole outlook on certain parts of life. For example, if your down about something and you listen to a blues song, you will probably agree with what the artist is saying because you will believe that the artist feels that way to. These three ways of manipulation can change the listener somehow, so therefore the manipulation is successful.
