The linked article mentions "the agency that collects music royalties in Canada," which should be understood to be a separate entity from the Canadian Recording Industry Association.
It's worth pointing out that there are several different agencies and several different sections of copyright law at work here. Purchasing a song for your own use and playing a song in a public place (or over internet radio) are two different things. I often see people in the US confusing the RIAA with ASCAP and vice versa, and a little clarity might be helpful.
So, in the US:
The RIAA represents distributors and publishers.
ASCAP and BMI represent songwriters and publishers, who are supposed to get a royalty when a piece of music is performed or played in a public place (or over internet radio).
SoundExchange represents performers or recording copyright owners, who are supposed to get a royalty when their recordings are played in a public place (or over internet radio).
So when all hell breaks loose and Justin Bieber does a cover of Michael Jackson's Billie Jean that is then streamed over Pandora, Soundexchange would collect royalties for Bieber's performance and ASCAP would collect royalties for Michael Jackson songwriting. If the original Billie Jean is streamed over Pandora, then Jackson would be (I believe) entitled to royalties as both the performer and the songwriter. These are performance royalties and are typically paid by the entity playing the recording (in this case Pandora).
When 100 trillion pre-teen girls try to buy a copy of Bieber's version of the song, they pay iTunes or WalMart or whatever, which is then supposed to pay the distributors. These are not performance royalties and are not administered by ASCAP, BMI, or SoundExchange. When you, out of morbid curiosity, illegally download the track, the RIAA will sue you to the tune of $xx,000,000 on behalf of the distributors.
I say this because it's important to know that even though these organizations are related, they are not the same. Also, performance royalties in most cases actually make it to the artist, so I'm hesitant to hate on ASCAP (I'm a member) although sometimes I wish they would just chill out a little bit.
