Whereas many would say Burn it Down, I'll Be Gone, or something of that nature, my favorite would be Roads Untraveled. When I talk to people about that song they say 'yeah it's a comforting song' or something like that, but to me there is much more to that song . . . it actually means a lot in relation to my life. And the guitar solo is great as well, probably one of their best solos. It's just . . . almost like it's magic . . . I can't explain exactly.
What is yours? =)
