I generally like the way Apple’s iTunes orchestrates my music collection, but sometimes it hits a wrong chord on the older and more eclectic CDs transferred to my computer. That’s why hundreds of songs in my iTunes library are missing the proper album artwork or have been lumped into loosely defined categories that don’t truly describe the music genre. For instance, iTunes’ automated identification system believes that some songs by the B-52s, the Jimi Hendrix Experience and the Byrds all belong in the generic rock section. But these birds don’t really flock together, do they?
