You can set equalizer settings for each individual song in iTunes, or you can set the global equalizer. But I have 5000 songs, ranging from jazz to rock. Is there any way to set the equalizer automatically for each genre (ie, use Rock for rock music) without having to set each song?
If you turn on "browse by genre" in the preferences, you can easily select each genre in the browser, do a select all, and assign eq settings.
