A spinoff of the copyright infringement thread, a question of ethics I pose to you. Let's face it, those of us that are skilled at audio engineering have a bit of a picky ear when it comes to music. I think it's safe to say that a majority of us have encountered a few songs they really liked, but couldn't stand at the same time because they were mastered poorly and the EQ is noticeably unbalanced. Now many of us also have programs to remaster audio tracks with reverb, normalizers, GEQ's, and all sorts of fun processors. That said, is it ethical for someone to go in and remaster a track to their liking? State your answer, your case, and additionally how that does or does not differ ethically than playing a track in a media player, stereo, or PA, behind a processing chain.
