Yeah the discussion that's going on here is pretty useless. We're talking "this band is good, that one is bad" and "this band is overrated, that one is as good as they're reputed to be."
The truth is that we're talking about
opinions and nothing else. Taste in music is one of those things where there are no absolutes. Even if 99% of all people agree that Beethoven was a great composer, it doesn't mean that if someone feels that his music just doesn't reach them their opinion isn't valid from their perspective.
There
are absolutes in this world, I believe. Absolute truth, unconditional love, ice cream, things like that. What is or isn't good music isn't one of them.
As amusing as the guy on
http://www.youhavebadtasteinmusic.com is, and while I pretty much agree with him, he's not absolutely right either, even though he has a website.
