I am glad you brought this up. It was in my speech, but I just didn't get around to it.
I know there was a lot of discussion about that, but I strongly disagree with a mandatory registration regime. For one thing, our copyright registration regime was designed to deal with an existing system, which is voluntary registration. It's really not equipped to handle the administration of a mandatory registration regime.
Putting that aside, registration just isn't necessary. Right now publishers and songwriters register their songs with SOCAN and CMRRA, which cover 99.9% of the market, and that system works very well. Commercial users who license songs know how to find copyright owners within the existing system, so they properly clear the use of music.
Introducing a second registration system that is operated by the government is going to require a significant amount of time, resources and money, and I'm not sure—
