Of course we do. It wasn't the artists who demanded the extension in the first place. They didn't seem to care and were happy with the 50-year span that has existed for who knows how long.
Ever since talk about this began, what I have been most curious about is this: what happens to music that, prior to this becoming a reality, passed the 50-year mark but still has a while to go before the 95 year mark? Typical law would say that that music would be exempt and cannot be huddled into this new timeline since it has already passed the previous mark of the previous law. However, I guarantee you that someone somewhere is trying to find a way to pull them back in and even collect royalties for the time in-between the 50-year mark and today which they are not due.
