Another thing I've noticed is Spotify's listing of many 'remastered' tracks. That's fine, except that they often no longer make the original track unavailable. The remastered tracks are much 'smoother' among other things, but to me sound very homogeneous, blending in with everything else and lacking character.
Remastered often equals compressed to the max. It means that soft passages become as loud as the loud passages. Read about it more by googling 'loudness war'.
