What does Usher think of Trump using his song "Hey daddy" on the Whitehouse page?

I’m not sure what to think of this. I am not familiar with Usher and have no idea how he feels about trump and the current administration. Likely he is a member of a performing rights organization if he composes his own music and lyrics. The author(s) of the particular song are undoubtedly members of a performing rights organization such as ASCAP, BMI or SESAC, along with the listed publisher(s). The PRO will collect royalties for use of this material under a licensing agreement. This happens with no notification to the composers, they simply see the royalties added to their accounts. They are not automatically notified of the license holders, but it can be relatively easy to figure out. They can then forbid the entity from using the material and it becomes a legal issue. If the entity uses the material without a PRO license they will be billed for the license type by the PRO. If they ignore this, they are sued and fined.
