An anonymous reader writes "DJ Danger Mouse's The Grey Album, a remix of Jay-Z's Black Album and the Beatles White Album has become a online music sensation, even getting reviewed in Rolling Stone though only 3,000 CDs were ever made. Now EMI, which controls the Beatles copyright, is trying to shut the album down. They've sent cease and desist letters to Danger Mouse, a handful of record stores, and websites that have hosted the songs. Wired News is reporting on the backlash that has ensued, led by anti-music industry group Downhill Battle, who insists that the major record labels are stifling creativity."
