Think what you want about Bob Dylan’s Nobel Prize for literature (and believe me, the blogosphere is awash with polarising opinions) but the famously recluse troubadour has unwittingly opened up an interesting and necessary debate: can song-writing be considered literature in its own right?

My gut feeling would probably shout out to let songs be songs and let literature be literature. Yet, somehow with Bob the lines get pretty hazy. He is one of the few performers who can lay claim to having a foot on both genres.
