I've long hated the HearYa and especially the palms out sounds blog scrapes. And I'm not the only one. I know that most of the posted songs (most of them remixes of extremely varying quality) eventually get a handful of bumps, and a small percentage "make" it whether they deserve to or not. But man, they really pile on the dreck for me. matttynabib posted some well thought out points on the site forum just recently, but I think its worth mentioning here.
In my opinion, the61 is "mature" enough not to need automatic infusions of songs from anywhere. The few gems that get entrained in the blogs are tarnished because they have no artist support on the site itself - scraped artists may not even know their songs have been put up here, and thus artist and fan get no chance at interaction. All in all it's a net minus to me.
This is more of a rant than a thoughtful analysis, but what good is a blog if you can't rant every now and then?
