I have listened to David Bowies last album Black Star many times. I think most people will agree that it's some of his harder-to-digest work and it took me quite a while to warm up to it. In fact, I am probably still in that process. The only reason I am willing to keep listening is that I know that Bowie was able to create music that affects me deeply so it's likely to be worth it. And even better, in my experience, the music that I have to warm up to tends to be what I love the most over the years where as the refined-sugar stuff tends to please me for a week and then fades. My point here though is that I would not know this about David Bowie if it wasn't for his easier work and all the promotion that he did/had. I think many artists go through a process of creating music that is more broadly appealing with time (for instance, Amy Winehouses Back to Black is easier to digest than the previous album Frank). Maybe this is because they want to reach a broader market, or maybe it's because they develop their ear to be better at making stuff that "works", I don't know. But I am grateful for the effect even so, as it seems to be the way my brain deems a new artist worth listening to. But promotion is definitely necessary as well. And this same pattern applies to the other arts just the same.
