My Byrds albums rankings:
Notorious Byrd Brothers (pretty diverse, great spacey vibe, two great Carole King songs, no bad songs).
Fifth Dimension (would be a reasonable #1 except I'm the only person who doesn't like "Eight Miles High". A bit hit-and-miss but a handful of really great stuff and maybe their best guitar work).
Turn! Turn! Turn! (maybe their best vocal harmonies, a couple great Gene Clark songs).
Younger Than Yesterday (I'm tempted to put this lower because there's three bad David Crosby songs on here, but most of the rest is good, including all the Chris Hillman material)
Mr. Tambourine Man (a couple great Dylan covers plus "Bells of Rhymney", but too much lackluster stuff).
All the rest (I haven't heard all of them and I struggle to remember the ones I have. There's the occasional good song though.)
