old: Neil Young "On The Beach"
(from 1974's startlingly non-Harvest sounding Harvest follow-up)
new: Willis Earl Beal "Take Me Away"
(2012's aspiring genre-polyglot plays loops with the blues)
borrowed: Destroyer "Leave Me Alone"
(Destroyer's New Order cover sounds more like Destroyer than NO. A proper cover borrowed from Mikayla C.)
blue: Joni Mitchell "River"
(Nothing sounds quite so Blue)
