When longtime Apple journalist and fan Jim Dalrymple is angry with Apple, you know something’s wrong. Dalrymple has announced on his blog, The Loop, that he’s “done” with Apple Music after it wrecked his extensive iTunes library. The first problem arose when he tried to add songs from different albums that iTunes saw as duplicates and ignored. Later, it jumbled up his albums, refused to sync between devices, and when he disabled Apple Music, it took 4,700 of his songs with it. “I trusted my data to Apple and they failed. I also failed by not backing up my library before installing Apple Music. I will not make either of those mistakes again,” Dalrymple said.
