Spotify's latest iOS app update rolls out today and adds a new equalizer to playback functionality. "A lot of our users have been asking for a built-in equalizer for a while now and it's currently one of our most requested features on iOS," says Sten Garmark, VP for Product at Spotify. The update also folds the Discover function into the Browse tab on iPhones and adds a redesigned Artist page to the iPad iteration, featuring musicians' latest releases and... merchandise. Android users have been able to add third-party equalizers to music playback on dedicated music apps for years, although there's no word from Spotify as to when these new feature will hit Google's mobile OS. We're hoping that equalizer will help even out music playback -- even if you're only packing underwhelming in-box buds.
