Ok, so my neighbor and I got into a friendly and kinda heated debate earlier today. The definition in question was musician. Simple enough, right. Well, I guess I was wrong. He brought up Skrillex, to which I kinda internally rolled my eyes. I knew where this was going.... Anyway, I find this coming up more and more. As a musician, it seems fairly obvious. I made the argument that Skrillex (among others) are more arrangers or composers for a lack of a better term because they actually do not play any instruments. He countered (quite wisely I might add) that you also have lead singers. He asked if I would consider them as musicians. My answer was no, they do not play any instruments. He then brought up a great point. While they do not play anything, they do have to remain on key while applying the craft they have been give. Just curious on everyone's take on this. Since we are now in a world where there does not have to be a single instrument played on a recording, I feel this debate could start happening more and more. Your take?
