I'm not a religious sort but I like to listen to hymns and hymn-like songs when I'm tying flies or futzing around in the garage. I find them uplifting and soothing and the more familiar the tune or song the better, so as not to distract me from my labors.
Whether it comes via a folk or blues singer, a string band, a choir or a symphony orchestra, whatever, it's all good.

Eva Cassidy left us all too soon but she also left us with some wonderful recordings and the posthumous release, Simply Eva might be my favorite. Just that gorgeous voice and her guitar. Here is the pared down version of Wayfaring Stranger from it-Wayfaring Stranger

My all time favorite melody may be the one used for Be Thou My Vision (it was also used for another hymn, Lord of All Hopefulness and the Irish ballad Banks of the Bann, not sure which one came first). Here it's performed by Michael Card with Craig Duncan on fiddle, who also arranged and produced it. That man, Duncan, is responsible for a mind-boggling amount of great music-Be Thou My Vision

The Grateful Dead produced what I've heard described as a Buddhist hymn with Ripple. I'd have linked the Dead's version of this Hunter/Garcia classic but I think it's been kind of over-exposed on Classic Rock radio. I never thought anyone could sing this as well as Jerry but Dale Ann Bradley gives him a run for his money-Ripple

In 1953 there was a movie released called Titanic starring Clifton Webb and the wonderful Barbara Stanwyck, not to be confused with the excellent A Night to Remember from 1958, this one was more of a melodrama but I was greatly moved by a scene from it when passengers on the sinking ship sang Nearer, My God to Thee, an event that may or may not have occurred. The Lower Lights perform it here with a nice pulse- Nearer, My God to Thee

The closing number of Ken Burn's excellent Lewis and Clark documentary was the hymn Beech Spring, aka Beach Spring, it starts out with what sounds like an octave mandolin or a mandocello and then a Native American flute and drum join in, highly fitting- Beech Spring

One more from Simply Eva, Curtis Mayfield's classic People Get Ready People Get Ready

I could go on for awhile, there might have to be a part 2 someday.
