this is an insanely hard question, but in the end bob has been much more influential and imitated in the grand spectrum of songwriting and song.... he has had his music covered by elvis, jimi hendrix, eric clapton and much much much much much more.... neil young is fucking sick... greendale is incredible and he's getting better with age, but bob is a prophet.....
impossible to compare, there both amazing, but if they were reading this, they wouldnt want us to have a 'winner'
DL or buy an album that has bob's 'visions of johanna' on it, or desolation row, or blowin in the wind or hard rain..... his song to woody guthrie is phenomenal as well
there both underrated, yea i said it
Jah burn dah roots/and love dah youths
