Saga Music,
Although generally I do agree, from a gaming point of view, reverb can be used to simulate a different environment the song is being played in. Although it indeed destroys what the song would normally be in, one could in theory have a desktop theme that would act like a cave with a reverb effect to simulate that, being able to switch on the fly.
But yeah, I would not play music for fun after that. Just wanted to point out that I can actually think of one reason why anyone would want to add reverb everywhere while they shouldn't.
