It's the snappy, funky signature-motif that gets stuck in my head. I keep thinking that it doesn't really represent the overall sound of the song at all, but that isn't true. I just relistened, and this thing is pure funk fusion and a lot more agressive than I'd thought. In my memory, it's always a little slower and a lot more melancholy—to the point where the lyrics could as easily be "My Love Is A Lie" as the true version, and I somehow imagine it's by The Alan Parsons Project instead. But no:
My Love Is Alive
Oh, memory, you have failed me. Is this where things are headed as I get older?
And now I've earwormed myself all over again...
