The song doesn't use power chords but if you are playing it on guitar it sounds better just playing the root notes. Basically it's [Verse and Bridge:] A A# A A# A A A A# A You can figure out the rhythm. [The chorus is] A Ab A A# A Ab A repeated over again That's pretty much it for the chords. Lame song, I know, but catchy and chicks dig it which is why we all play guitar in the place.
