...numerous courts have held the opposite: that joinder of defendants who allegedly downloaded music using the same ISP and the same file-sharing program is improper. See, e.g., Interscope Records v. Doe, No. 04-0197 (M.D. Fla. Apr. 1, 2004) (severing defendants who used the same ISP and same file-sharing program); see also BMG Music v. Doe, No. 06-CV-1579 (N.D. Cal. July 31, 2006) (severing defendants who used the same ISP); BMG Music v. Doe, No. 04-650 (E.D.Pa. Mar. 5, 2004) (same); Twentieth Century Fox Film Corp. v. Doe, No. C-04-4862 ("[The allegation that defendants used the same ISP] amounts to no more than a claim that ten unrelated defendants engaged in distinct and unrelated conduct.").
