The Matrix are a group of songwriters that have written songs for Avril Lavigne (Complicated, With You, Sk8er Boi), Britney Spears (Me Against The Music, Toxic) Liz Phair (Why Can't I, Extraodinary, etc) and I believe they worked with Hillary Duff. I forget. Those are the only notable artists and songs I can remember off the top of my head. But they're known for writing chart topping songs. I like some of the work done by the Matrix. And remember how Vanessa promised that everyone would recognize this next CD? As her second CD even? I think with a songwriting group like the Matrix behind her, she may have her next hit even if it's not through means we would wish her to have it. But everyone's (Including myself) been bitching about her not getting the recognition and air play she deserves and this may be the means to let her do so. So I don't see what the big fuss is. It's music, and it's not the first time she's co-written with anyone before.
Haha, I keep editing this post. But Linda Perry is a pretty big name herself as well, she produced P!nk's Missundaztood which sold very well, and she produced Christina Aguilera's last album... right? Or at least co-wrote a few songs with her, and that did extremely well too. If Vanessa's working with people such as Linda and The Matrix, one could only assume that she's preparing to kick MTV in the balls.
If they have balls.
