Paul Cox hits the nail on the head:
I only visit a handful of mp3 blogs. Not that I’m above becoming a junkie, but because I really enjoy finding out about things all on my own. Also, the number that were created within the last year just makes following them all daily an exhaustive task. But I do want to pick one nit in particular: Scenestars. They’ve been guilty of this sort of self-important carelessness in the past, but today they’re hosting three (!) fucking tracks from the New Order album which isn’t even due in stores for two more months. It’s bad enough when three separate mp3 blogs will post different tracks from any given record, but to have them all in one place is just a gross mishandling of the responsibilities that come with running such a portal. (So is exploiting the good nature of your readers in an effort to stock up on free iPods and other tech trinkets, but I’ll save that gripe for another day.) So, fuck Scenestars and any other mp3 blog that carries on in this manner. It’s about giving people a taste of what’s coming, not about supplying them with a full quarter of the material from a highly anticipated record. (source)
I don’t go to any mp3blogs mainly because I can’t keep up with them. If you can, god bless you because you’re a better person than me.
But if you’re going to run an mp3 blog, do it responsibly. The RIAA love to sue. Always remember that.
