Are there court cases where music being sampled for dance is brought up?
If the big music producers were smart/had the time, they'd start selling royalty-free/stock songs to the smaller producers/gyms/schools to use for their music. If they consistently turn smaller programs/schools away because they cannot fit them into their schedule, make some stock mixes, sell them, and collect the money from them while you're working on the big gym's mixes. In theory, it's a win-win for everyone. Passive income is an amazing thing and this new ruling has created a potential gold mine for the people who can do it.
