I don’t buy many CDs, but I recently bought a "best of" Velvet Underground album, and bought "THEM…Again", about a year ago, after reading how "important" they were. It may have been BS, but both these albums contain songs that "top" rock stars consider special. My most recent buy, "Modern Times" by Bob Dylan is not as good as I had hoped. Maybe it will grow on me. IMO, no rock band has turned out more great stuff , over such a long career, as have the Stones.
