Not long ago, a three-CD, 50-track collection of America-themed songs that’s titled, appropriately enough, Song of America, arrived in stores. What’s so special about that? Well, aside from the fact that it features freak folker Devendra Banhart (“Little Boxes”) and Springsteen acolytes Marah (“John Brown’s Body”) alongside the likes of soul diva Bettye LaVette (“Streets of Philadelphia”) and Chevy rocker John Mellencamp (“This Land is Your Land”), the set was executive produced, oddly enough, by Clinton-era Attorney General Janet Reno (no, “Burning Down the House” isn’t on there, but thanks for playing). Apparently, she and her niece’s husband, a record producer, conceived the idea a few years ago, and even made a trip to the 2005 Grammys to get artists to sign on to the project. “I just hope that people will have the opportunity to hear [Song of America] and to see what songs can do to inspire and to motivate and to give people a sense of themselves,” Reno recently told NPR.
