Apple Music Classical is out! MacStories has a detailed overview here.
Why this app needs to exist and exactly what kind of problem it solves has been covered a little bit here on the blog and on the podcast over the years. I have been using and recomending IDAGIO for some time now.
I have been using Apple Music Classical a lot since last night, and while it leaves a lot to be desired (like an iPad, Mac, and car app!), it is good enough for me to replace IDAGIO.
The fact that it links to my existing Apple Music account and library means that I can continue using the standard Apple Music app in combination with it. One library for all of my music, but two app interfaces to interact with it, depending on which context makes the most sense.
I plan to cover this app on the podcast some time soon. You can download Apple Music Classical here.
