By the way, if you tag your questions "ESL" and "English" you will get less confusing answers. Someone tagged this "politics" and it may not be clear to others that you are asking for basic reading comprehension help to learn a foreign language and not starting a political discussion that you can't follow.
I find this part confusing ....would not have bought the music if that were the only way to get it..
This is a unfulfilled hypothetical conditional statement (you don't need to know the term, I just use it in case your grammar books do) and the sentences can get confusing here because of how tenses are used so differently in such hypothetical conditional statements. For example, if you are talking about the future you use past
, if you are talking about the past you use past perfect
So here is the same statement, slightly rewritten for clarity, and in different tenses (just for illustrative purposes, the first one actually isn't an unfulfilled hypothetical anymore):
"If buying the music is the only way to get it, they will not buy it."
"If buying the music were the only way to get it, they would not have bought it."
