Why are these sources pertinent to your article:Technology has influenced the (digital) music market

I’ve already written the article and I’m stuck at source criticism. I need someone to help me with this assignment by editing my article to get a good grade. This is a well-written article about an interesting topic. You do a great job captivating your readers with your introduction and your article is easy to read. Adapting your writing style to different types of genres and audiences can be a bit of a challenge but you improved your article well according to my comments. My only concern is that you have not evaluated each source separately. You mention that all of your sources are opinion pieces but what does that mean? Is that a weakness or strength when it comes to credibilty? Why are these sources pertinent to your article? Source criticism is an important part of this course, and since you did not evaluate each source in article part 1, I would like to ask you to expand on your criticism a bit more here. Please read my previous feedback in article part 1. To clarify, just revise your source criticism and send back your article for a final assessment. Feel free to make other changes as well.
