Yeah, Musescore doesn't quite fit though.

It doesn't really work like any other DAW.

It has a strong focus on composing sheet music, as opposed to recording and producing full tracks.

Well yeah, that's what Finale is and what this thread is about. If you're talking about standard DAWs then your initial comment was a non sequitur

I don't see how wanting a "blender for music" in response to this news is a non sequitur.
