There is no longer a forum. You can write reviews, and they'll post them, but watch out - I wrote a few praising the album in question but also rather strongly urging the reissue of more of the same artist's material, and they got yanked quicker than The Beatles' Butcher Cover. It's a colorful site, kinda neat visually, and lots of sound samples, but it's TOTALLY corporate.
However, A&M records has a forum...
