A Bob Dylan tribute is among the new arrivals in stores today.  The human rights group Amnesty International is behind the compilation album "Chimes of Freedom: The Songs of Bob Dylan Honoring 50 Years of Amnesty International." The 75-track, four-disc set includes contributions from 80 artists including Pete Townshend, Jackson Browne, Joan Baez, Bryan Ferry, and Carly Simon. Participants covered songs Dylan either wrote or made his own for the project.
