Assembled by Washington, D.C.’s Future of Music Coalition, Rock the Net features tracks from 16 artists who support a free Internet — that is, an Internet in which everyone has the same level of access to legal content. Guster, Bright Eyes, Aimee Mann, Wilco, and They Might Be Giants all dot the star-studded track list, which also features the Wrens’ first new song in five years. – Andrew Leahey
