Just looking at a remastered track in Spotify's catalogue. It's Neil Young's
I've Been Waiting For You. The screen shot shows the start of the remastered track (from the album
Neil Young (Remastered)) followed (after the gap) by the same section of the original taken from a compilation.

To me, the remastered version is horrific and hurts my ears, while the original sounds beautiful - albeit with the effect of the vocal sitting above the instrumental mix with the bass panned fairly hard to the left. It doesn't sound like a modern mix, perhaps, but is rounded and warm. The remaster has the bass more in the middle and the vocal seemingly lower in the mix, perhaps with some zingy EQ and extra compression.
Goodness knows what horrific processes are involved in doing this. Had it been the other way round, I would have congratulated them, but for me the remaster sounds horrible.
