Garth actually had his own streaming service GhostTunes, which was created solely to only host his own music for streaming until he realized what a dumb idea that was.
Tbh seems like he knows his audience. Surely plenty of people still buy CDs for their car stereo rather than streaming Spotify or something, especially the kind of people who listen to country music.
I can respect those that tried to resist the onset of streaming, it really did/does screw over artists.
Garth has a net worth of like $300M so I guess it worked out pretty good
