I see what you're saying.
The original poster was describing reverb/echo presets in the DSP: Hall, Stadium, Concert, etc.
You're talking about EQ presets: Jazz, Classical, Flat, etc.
I find both things distasteful. The first thing assumes that the original producers didn't use enough reverb in their recordings and you need to add more. The second thing simply ignores the whole purpose of an equalizer and assumes that there's a such thing as a "one size fits all" equalizer preset.
I could see having the equalizer come pre-loaded with presets, as long as they were editable, and they weren't labeled by genre. For example, I would just retch if they said "Jazz", "Classical", etc., but I would have no problem if they were labeled "Bass boost", "Mid Cut", "Less Bright", "Enhance Vocals", etc.
