It's the bicycle chain of songs this week; every song will somehow be related to the last until we tie the chain together at the end. Included: Modern Lovers; Amy Winehouse; Donny Hathaway; Ray Charles; Willie Nelson; Sheryl Crow; Aldus Huxley; Bernard Harris; Stevie Nicks; Car Seat Headrest; and back to Amy Winehouse again. See if you've got the musical chops to follow the chain.
