This is a rant. Sorry. Hang with me. Or lock it. I don't really care.
There are a few individuals who, whenever someone has something disparaging to say about a band, immediately respond with "why don't you have anything positive to say?" or "keep your opinions to yourself" or something equally inane. This is lame. This is obnoxious. This defeats the purpose of any sort of discussion on music in the first place.
You don't like people critically reviewing music? Well, shit, you probably shouldn't read album or concert reviews in your local paper, alternative or otherwise. I mean, they're going to dislike some of the stuff you love. And damn, you certainly shouldn't read Pitchfork or any other critic website, because they'll just thrash your favorite bands.
You don't like people making clever jabs at your favorite bands? Well, Jeph ought to just keep music out of his strip entirely. And Mitch Clem should stop writing
Nothing Nice to Say. And SomethingAwful should just shut Your Band Sucks the fuck down. Because everyone knows making fun of bands other people like, even when it's done in a clever manner, isn't funny. Not at all. Not in the least bit.
People making cracks about music serves multiple purposes. It can be an honest to god criticism of the band. Is that wrong? No, not really, if you take music seriously, especially if you write it yourself, you are constantly looking things that work well and things that don't work well, so you become honed to look for such aspects of various pieces of music. Honest criticism, such as, "man, their lyrics are really cornball. The music itself is fine, but they need to have someone else write their lyrics" helps understand the music better, and for people like me, helps validate other reasons for liking a band, such as style, interplay between instruments, musical skill, etc. It can be a way of taking down a band that takes itself too seriously (and yes, there are tons of these out there. I like quite a few myself. I mean, I love The Mars Volta to pieces, but there are definitely an assload of jokes that can and should be made at their expense.). It can be a way of injecting some humor into an otherwise dull conversation. Hell, it can be a way of telling other people with similar taste to avoid wasting hard-earned money on a particular album (Trail of Dead rocks, but I wouldn't touch Worlds Apart even with Hazmat gloves). At the very least, it might make someone laugh (god forbid).
So seriously, there is nothing wrong with arguing about the merits of a particular band. There is nothing wrong with making a short snarky comment about a particular band. So seriously. Chill out. The world is a better place when people disagree occasionally.
