Critical Reading, Critical Literacy, and Content Area

For a music class (with some exceptions), I do not think critical reading or critical literacy plays a significant role, relative to other subjects. Critical reading may play some role in that students must be able to connect their previous knowledge to the current knowledge in the text to facilitate learning. However, unlike history or politics, music usualy does not entail one's perspectives or opinions. Also, critical literacy really provides no insight because there is no power relationship inherent in musical concepts. An exception may be a music history class because a music history text may contain the author's own interpretation of historical events in relation to musical developments. Also, sociological, cultural, or political factors may have influenced the text's historical interpreation.
