iTunes being shiat is a big reason why I don't listen to music as much. I am annoyed with constantly having to figure out what new crapped up way iTunes does X, annoyed with the integration of Apple Music into the iPhone Music app, and annoyed with all the maintenance. My music is a 250gb waste of hard disk space. Riddle me this: why does the iPhone Music app require cellular data access when all I want to is play music local to my iPhone device? WTF is the app doing? I don't subscribe to the stupid music match function so what exactly is it doing?
