Going by number of times played, it has to be Long Road Out Of Eden by the Eagles. The Weakerthans' Reunion Tour would be second.
Single of the year:
R.E.M.'s cover of #9 Dream wins by default as the only single I bought.
Gig of the year:
Country Joe McDonald! He was at Woodstock, yet there he was on stage just a couple of metres from me! How cool is that? Well, perhaps it's a little sad.
Musical discovery of the year:
Woody Guthrie, who's opened many other musical doors for me.
Tracks that will always remind me of 2007: (in roughly chronological order)
The Ballad of Easy Rider - The Byrds
This Land Is Your Land - Woody Guthrie
Tangled Up In Blue - Bob Dylan
Wolves (Song of the Shepherd's Dog) - Iron & Wine
Forever Young - The Pretenders
Waiting In The Weeds - The Eagles
