The obvious one must be Fa-fa-fa-fa-fa by Otis Redding, shirley?
Atmosphere by Joy Division.
Pretty much anything on Emmylou Harris' Red Dirt Girl, but especially Bang The Drum Slowly or Hour of Gold.
Also pretty much anything on Nick Cave and The Bad Seeds' The Boatman's Call.
Or, while on Cave and The Seeds, from No More Shall We Part, the title track, As I Sat Sadly By Her Side, Love Letter, Sweetheart Come.
Jorma Kaukonen - Genesis.
Most everything off Peter Hammill's Over.
Van Morrison - TB Sheets, Slim Slow Slider.
And on an instrumental note (tee hee), most of Explosions In The Sky's The Earth Is Not A Cold Dead Place.
I'll stop there...
