I think he's looking for what I am as well... which is more or less a total equalizer overlay on top of ALL sounds, or more specifically, media sound output. Sadly enough, there is no app or program available for this at this current point in time hyperrave.... I've searched long and hard as well.
Just an FYI, try using LastFm from the market, it's got perfect sound quality, and the bass is 150% there, unlike Pandora whereas our phone is 'unsupported', which is their way of saying they don't want to update the application and fix the hundreds of issues with it.
