I have a question about the pronunciation on the conjugation page of the verb étudier, I  looked it up to understand the difference between present and imperfect of the nous and vous forms.

I found that it gives je étudie rather than j’étudie and that the il and on forms of "étudiait" are pronounced differently from "elle étudiait". Is this correct?

Why is the sentence fragment "J'écoute du Beethoven" and not "J'écoute à Beethoven"? When would someone use 'écouter à' vs 'écouter de'?
