Let's see, invented folk-rock by merging Dylan with the Beatles, perfected the Rickenbacker chime 'n' jangle without which Big Star, REM, and Tom Petty, to name just three, would be unimaginable. Made two brilliant folk-rock albums, two wonderful psychedelic albums, and then merged psych beautifully with country for a fifth before releasing a landmark country/rock hybrid that has influenced literally dozens of today's country or alt-country acts, to say nothing of countless LA folkies and rockers like the Eagles. I can't imagine rating another American band higher unless it would be the Velvet Underground (no, not even the Beach Boys). And I can understand how opinions about the VU might be polarized. But the Byrds? Not in the top 10? Hogwash!!!! Your servant, Jon
