People acting like laws don't exist. She has every right to do so. You may like or not like it, no one forces you to consume her music.
And since when wanting to make more money is the bad thing ? It is a business, not a charity. Again, people are free not to give her more money, but how could you force someone to put their work for free on the market ? Would you do it ? Her being rich doesn't strip her of those rights.

Taylor is suing people???, Who???, where are the legal papers to prove that??? and a cease and desist letter is not a legal lawsuit, show me.

Not you making this about Taylor and talking about "some other musicians" when it's almost 200 artists (including Paul McCartney, U2, Elton John, Sheryl Crow, Idina Menzel, Carole King, Jack White, Amy Lee; just to name a few respected people) and a lot who are popular on here (Christina Aguilera, Katy Perry, Lady Gaga, 5H, The Chainsmokers, Pink, Britney etc).
