I wouldn't say I listen to "less" metal than I did 5 years ago, but the metal I listen to now is definitely very different.
5 years ago I was totally into much more classic and traditional metal, but in recent years I've found a lot of Prog and some Power Metal that I dig.
Actually, now that I think about it I do technically listen to less metal than I used to. Metal was all I listened to 5 years ago; since then, my comfort zone has become a lot of the awesome 70's ProgRock, much heavier ranges of metal and the Beatles. Ooooh, have I become fond of the Beatles in the past 5 years.
My heart went from much more traditional stuff to Symphony X and Dream Theater, which led to a whole lot of stuff. It led me to the ProgRock like I said (I.E. Yes, ELP, real Genesis, King Crimson, Rush, you get it.), and it also led me to more unusual bands. I've become fond of Mastodon in particular, and Meshuggah as well. Meshuggah was a band I never fully understood until recently. And in understanding those bands, it opened me to more metal. And at the same time, the classic Prog took me in another direction with thinking about music. That's how I came to obsession over The Beatles.
