I started ripping SACDs and importing them into my library in addition to the PCM tracks imported from iTunes, and noticed something really strange: every single multi-composition album is now appearing as one album per composition. Sure, I can merge them, but I am not going to do that for every single album out of 2170 in my library. This also happens for newly identified albums, e.g. Ton Koopman’s recording of Bach’s French Suites each suite appeared as a separate album, even though it is the same in the Identify dialog.
I don’t know when that regression started, but it’s very obvious so it’s probably recent.
I am deleting the PCM RedBook variants of SACDs tracks as I rip them to avoid duplication, but the duplicate albums also occur for PCM-only tracks/albums, and also for single-disc albums.
