Isn't SOCAN in Canada? If it is then they are out of our territory. I have SoundExcahnge contract too.
What I think is that if those artists, all of them European, don't have their royalty collection in the USA and I play their songs, there is no way they can sue me. I'm in USA and I have all lic possible in this country. If they do not have their legal stuff here, then that is their problem. Having lic from ASCAP, BMI, SESAC and SoundExchange, I'm supposed to play any piece of work in this country... That's what I think. Am I right?
Maybe, I'm too concern about this. Checking every song that I include in my station.
