Point I'm making is that if I relied on radio or (shudder) MTV, I wouldn't own either of these two albums today. The Internet is the best promotional tool the record industry has and it has the potential to sell millions upon millions of albums for them. So what if people end up getting some songs for free? How many of us taped off the radio back in the day? FM radio used to play entire album sides. I made many tapes off the radio back in the 1970s. As a result, I own most of those albums as CDs today.
The RIAA is so afraid somebody might get something for nothing that they are doing irreparable harm to their long term survival with these kind of tactics. I believe the expression is "cut their face to spite their noses."
A discriminatory approach - Yes. I believe this type of selective targeting is illegal. All are guilty but they will only prosecute some of them.
