on iPods, iTunes, winamp etc. Do you use them? I can never be bothered, seems like too much hassle for 3 minutes of music, just to have to change it all again for the next song. Plus, some highly skilled producer's put loads of work into the way a song sounds, I really can't see that me fannying about with a couple of sliders is going to make much of an improvement.
Mind you, I'm listening to Health with my iPod set to 'Electric' just now, and it sounds... almost the same, but with more bass. Which might be a good thing
