Okay, so they're not highly literate lyrics 'cause it's a techno-mantra stomp kind of a thing. a vocal sample saying "seven" forms part of the rhythm loop at times.
Seven ways to love, / seven ways to love, /
Seven ways to love, / seven ways to love, / yeah! /
Is enough to give you the basic idea...
