Musicality is a passion project for me, but my nights and weekends haven't been enough to keep up with the changes in macOS, tvOS, and the music services. I've fixed most of the issues, but I no longer feel good when people buy Musicality, even with the free trial.
I use Musicality all day, every day so I have every intention of getting it all working again, but I don't know how long that will take. Until then, I'm no longer offering it for sale. If you'd like, drop your email address into the form below and I'll notify you when everything is working to my satisfaction again.
