Anyone else use Promosquad?

I joined Promosquad a few days ago. It’s a site where they play demos of new songs and you rate them and leave comments.

Wow. Some of this stuff is incredibly lousy. I thought I had a fairly broad tolerance, but I’m giving probably 50% of the music an “I hated it” rating. I’m running out of ways to comment that a song sucks.

I have a feeling I’m not the right target. Anyone else using?
