Pulling an all-nighter and man, Amazon Prime Music has become awesome. Lots of superstars like Buddy Guy, ZZ Top, John Mayall and the Bluesbreakers, Joe Bonamassa, Janis Joplin/Big Brother & the Holding Company, The Who, B.B. King, Eric Clapton, Jefferson everything, even the freakin' Beatles and the Stones, plus great lesser known talent like Dan Baird and Homemade Sin/The Bluefields, Jim Suhler and Monkey Beat, Turnpike Troubadors, Blackberry Smoke, and The Devil Makes Three. Only disappointment has been Shovels and Rope's ensemble album "Busted Jukebox" - it can't compare to their Shovels and Rope-only albums, even though some of the people (Shakey Graves, Milk Carton Kids, even Emmylou Harris) are excellent artists in their own right.
I swear, Amazon Prime Music is now worth the price of Amazon Prime by itself.
