For Volume 2 of our Guilty Pleasures series, we revel in the freedom to create an eclectic flow—during these days of algorithmic radio—from Lotte Lenya singing “Mack the Knife” to a Japanese take on Archie Bell and the Drells’ “Tighten Up.” We look toward summer with music from the Kinks and John Prine, and cool down with tunes by Ramsey Lewis and Oscar Brown, Jr. Plus some listener-requested guilty pleasures from Bob Marley to Bonnie Raitt. Sit back, tune in, and indulge guilt-free!
