I play exactly what is in Version 2 of the Irreplaceable chords (http://www.ultimate-guitar.com/tabs/b/beyonce_knowles/irreplaceable_ver2_crd.htm.) but I think this might make a better bridge: Capo 3 Em D So since I'm not your everything Cadd9 How about I be nothing G Em nothing at all to you? A Baby I won't shed a tear for you C I won't lose a wink of sleep D cuz the truth of the matter is Cadd9 Em G replacing you is so easy... The rest of the song is just repetitions of G, D, A, C as shown in Version 2.
