As noted on this site, Ja Rule is clearly making comments about someone on the Remix to the Pledge with Ashanti and Nas. However, DMX may not be the target. If you listen closely, he starts by say whats up Suge, then refers to the “Dog” in question as “Bitch Dog” and comments that the rapper in question has curls… Hmmm sounds less like DMX and more like Snoop.
Note: He also says “murder would be the case,” another Snoop reference. I’d agree it’s about Snoop. You can download the track off KaZaA.
