Exactly. When I wanted to be in a, uh, "psychedelic mood," I'd crank up "Welcome to the Machine" or "Comfortably Numb," or "Have a Cigar." But that was after I listened to all my Moody Blues albums, which were far more musically accomplished and better produced.

Zep left a gigantic legacy of quality music. Too bad so many only heard or were influenced by "Whole Lotta Love," and wrote them off as a "heavy metal" band. They were a great English folk rock band, part of a long and honorable tradition. "King Arthur Rock" might be another label. "Ramble On," the pinnacle, IMO. "Rain Song," "Kashmir," "What Is and What Should Never Be," "Your Time is Gonna Come"...the list never ends.
