Not too long ago, I stumbled upon this blog. The author is a musician who has a podcast where he releases what he calls “Music to Pray By” (which is also the name of the blog). The music is piano based and I find it soothing and spiritual.
He also has an entire album you can download for free by clicking here (you can choose the entire album, specific songs, or you can download his podcast entries). I highly recommend it.
