I try. There's so much more to music, especially in metal (I see it more from metal artists than from pop artists) than just the beat and the song, there's depth of story, how YOU relate to it, every individuals experience is personal and special to them. And some artists take that seriously and it shows in the thought that they put into the songs. They're (metal musicians more so than other genres) modern day composers. Not just formulaic cookie cutter massive produced stuff for the right now. This is how they've outlasted all the trends and times, in 10 years time some artists will fall off the publics memory. But artists like Priest, Maiden, Metallica, Sabbath to name but a few, they'll be remembered in the history books.
