Let me try this and stick to the rules. I am only doing from Mystery to Me on.
Mystery to Me: Why
Heroes: Come A Little Bit Closer
Fleetwood Mac: World Turning
Rumours: You Make Loving Fun - Go Your Own Way (tie)
Tusk: Think About Me
Fleetwood Mac Live: Over and Over
Mirage: Straight Back (if Smile at You made the record then it would be Smile at you...an angry Stevie sounds so good)
Tango: Isn't It Midnight
BTM: Back of My Mind
Time: Nights in Estoril
The Dance: Everywhere
Say You Will: Running through the Garden
BuckVie: Red Sun
Honorable mentions: I think Oh Daddy has the most trippy Fleetwood Mac sound with the organ and guitar. Its the best musical track but not the best song (if that makes sense). Hold Me is the best FM single. Sara on the Live album is perfection but annoyed it is studio touched. Too Far Gone on BuckVie also is an honorable mention but I can live with my original list.
The lonely castanet gets me every time. IMHO Chris's most beautiful organ lines and most profound Lindsey guitar merged together. I wish the song had 12 minutes of play out.
