According to this I'm just "Blowing in the wind", but I like his songs sung by others, such as Nina Simone's version of "Hollis Brown", or Johnny Cash singing "Wanted Man".
I'm Tangled Up in Blue, too. Except that I'm not, by any means - there were two alternatives (Subterranean Homesick Blues, Lay Lady Lay) which suit me far better. But this was a minimalist 'quiz', was it not, which was a pity - if they'd worked a bit harder it could have been a lot more interesting.
During the past few decades I've occasionally amused myself by listing my top 50 Dylan songs (first did this just after 'Street Legal'). Always in the top 5 is 'Dirge' (from Planet Waves), or 'Chimes of Freedom'. Of more recent work, 'Nettie Moore' (Modern Times) and 'Po' Boy' (Love and Theft).
