Ask HN: Have you noticed your songs being swapped out with inferior versions?

Without my having made any change to my playlists or library I'm noticing songs I've had in my library for years are being swapped out with re-recorded or remastered versions and they're are almost universally WORSE than the originals. The artists are older, their voices are no longer at their peak and the accompanying band sounds different and somehow weaker. It's like I'm getting the off-brand version of the original song.
