I don't know whether the audience is to blame. I think it's all about promotion, about how much money a label pays the x, y magazine to promote its releases. They always promote the same stuff, again and again. Check the "album of the year" section and you'll see the biggest bands on top. And it's not like they don't make good music, but there are lots of other bands that make a great job writing songs as well. It's always about promotion. Everyone is hyped when Iron Maiden is to release a new cd, even though it will never be as good as their old ones, just because of the audience's love and their nostalgia and the stuff they read on the media (I do not imply that they make bad music, but let's just be realistic here). The only thing that makes me happy is that there will always be some dj's who add underground or underestimated tracks in their playlists. They really help people around them learn some new stuff, even the lazy ones you're talking about. After that, it's all about passion. If someone is passionate enough, they will always look for something more.
