Earlier in the week I heard a great song on the radio: Charlie Haden's "The Left Hand of God." I went to iTunes to buy it, but was greeted with the note that it was an "album only" song, one that you can get only if you buy the whole album (!). I'll probably go 'head and get the whole thing -- Now is the Hour -- because it contains other cool songs, but I thought that MP3 download sites were created to let you get exactly and only what you wanted?!?
