"The Copyright Royalty Board (CRB) has set new streaming-music rates for 2016 at 17 cents per 100 plays on free, ad-supported services and 22 cents on subscription-based platforms. The rates, which were set on Wednesday by federal judges who serve on the board, are up from the 14 cents per 100 plays on ad-supported streaming and down from 25 cents on subscription services."
So, per the CRB, an artist is due 0.17 cent per play on a non-subscription-based platform. So on a typical OtC webcast where we might play 70 songs to an average of 25 listeners over the course of 5 hours, the artists as a group are owed $2.98 for that night's cast. (That's $0.0017 x 70 songs x 25 listeners.) And that is assuming that a royalty is owed on every song, which on OtC it isn't because of the age of some of the songs we play.
I've always said I would submit this kind of payment to an artist royalties clearinghouse, along with a formatted log of songs that were played, so that the artists can be fairly compensated for the music that gets streamed. What I have said I will NOT do is pay rapacious fees to rights organizations that make no provision for the scale and economics of the smallest tier of webcasters. The last time I checked, the lowest possible licensing fee obtainable through ASCAP, BMI, SESAC, and SoundExchange was around $1500 per year, which is more than 10 times the "fair" price as determined by the CRB on a per play basis for an operation the size of Off the Charts.
As you can see, the royalties owed from my little hobbyist webcast are so miniscule, it's hardly worth bothering about. Which maybe is the reason we hear of a lot fewer DMCA take-downs of streaming music casts, compared to a few years ago.
