Deep Hidden Meaning Radio with Nile Rodgers is really interesting as he sits down with composers rather than the singers to get the story behind the songs. The particular episode with Sir Paul McCartney managed to be rather epic despite being recorded remotely.
This is unexpectedly interesting as well. Somehow the blend of old and new sprinkled with personal stories made it sparkle. I got to listen the episode with Shaggy on air and she managed to get a rather intimate interview with him. Completely changed my perception of Shaggy that usually seems aloof.
