Here's my whole thing on this, I feel like it's tacky and unprofessional for USASF to bring this up on us last minute, but hey, that's just me.
I don't know why they have to wait so long to give out more information and what's allowed and what's not allowed. I think that since we are giving them thousands of dollars each season, we should get more respect than this and get the answers we deserve and not have to speculate, and then possibly start conspiracy theory's as to why they're getting sued. We deserve to know immediately. Not be told a "beat around the bush and vague" answers. Which is what's happening by most varsity reps in many facebook groups I'm in.
The dance industry (that I am heavily involved in) (studio wise) do not have this problem because each studio owner is required to pay all three licensure companies. (ACAP, BMI, etc) Also, the dance competitions are independently owned. They aren't bought by major brands like Varsity, or any other business that may be around that buys companies and become "sanctioned events" each competition also has music licensure from those three companies, and as a part of their laws, you CANNOT charge for events under certain music licenses. (Hence as to why most dance competitions are free, unless they're being filmed for the Dance Moms show, which is why on Dance Moms and Bring It you hear cover songs and not the original music pieces that were actually being played at that comp)
So to basically break it down, (in my opinion, and from past experiences) I FEEL like Varsity is truly getting sued for a more serious issue than just the legality of Cheer music.
EDIT: The dance studio world, also does not have an official government body like USASF trying to "legitimize" Dance as it is already considered an art form. So there for, there aren't live stream videos that you have to pay for to watch, etc. The majority of Dance Studios that are around, especially the professional training ones, want nothing to do with USASF, or have even heard of the program.
