I don't know about addicted... but I do love the sound of an electric guitar. There's not much music I listen to that isn't guitar based, one way or another. But I also love the sound of a voice, especially in simple arrangements that aren't swamped by elaborate production or studio trickery.
I guess what I really love is music that sounds like it's made by humans, not machines - the little mistakes, accidental sounds and slight mis-timings. And the guitar is wonderful for that, there are so many ways to change the tone with just the way you pick, or how hard you squeeze the strings. It's almost impossible to play anything exactly the same way twice.
I'm not so crazy about the sounds I make myself. I do pick up a guitar nearly every day, but maybe only for a few minutes at a time - and usually it's unplugged.
