Try guessing the chords on your own, firstly start by guessing the "main" note (with the small E string works better), that will be the root note of the chord most of the times. For example, when I first played DIsappearing Act this morning, first note I guessed was the E string on the 6th fret (--> A#). When you're more trained you can guess the full chords (and its modifications like minor, seventh, etc) just by knowking the progression it's in, or viceversa.But Google-ing the tabs and chords do NOT train your ear!!

PS. Just a tip, and advice from player to player. Trust your ear more than your eyes
