Two of the artists on today's music list are names I've heard my whole life. Yet, I've never heard a whole album by them before. Made me think of all the other artists I know the names of but have never actually listened to. Part of me knows you can't possibly listen to everything but it does make me think twice when I re-listen to something I've heard before. What should I listen to next is a choice between expanding horizons or diving deeper. Should you listen to something new or should you listen to something again and figure it out more.
