Videogame music "restoration".
@noiob Another friend of mine sent a link to a couple of these "restored" tracks, and while it's kind of fascinating, I felt as described in that article.
Another novelty that could be mistaken for "restoration" is the NCSF format for DS music. Some music benefits greatly from having top-notch sample interpolation... and some falls flat because the samples that were relying on a lack of interpolation to keep them sharp (chip-style sounds especially) become a muddy mess. Fascinating, but definitely not how it was "meant to be heard".
