Funny how different types of music can be jarring to some, and soothing to others.  As a child, I simply listened to the small record collection we had in the house. Later, as a teen I drifted into heavy metal, to my parent's amazement.  Now I like "calmer" music, including long-form folk, for instance Alice's Restaurant Massacree This is a digital download from Amazon.com but I consider it an extra bargain since it is so long (1/2 the album is this one track.) Kudos to this blog post about it at JamiesRunoutGroove.

(Although I still do like metal sometimes, for instance http://www.stream88.com/ has some real blast-from-the past metal bits.)
