"I don't wanta do any Blues or any sad songs"

Bob Livingston's quote reveals a desire to avoid certain kinds of music. He specifically discusses Blues and unfortunate tunes, which recommends that he is not interested in playing or listening to music that is emotionally heavy or melancholic. This could be because he is in a good mood and wants to keep it that way, or since he is feeling down and wants to avoid music that will make him feel even worse. It could likewise be that he just chooses other kinds of music and wishes to focus on those instead. Whatever the factor, it is clear that Bob Livingston does not want to engage with Blues or sad songs.
