There used to be an exercise that people who very much enjoy music would indulge themselves in that used the old 'if you were stranded on a desert island' theme. Given current technology and the tendency of many to 'stream' music and not play entire albums of music at a time, this thought exercise doesn't seem to get used all that often any more. The basic idea is that you will be stranded on a desert island and you can select only 10 albums worth of music to be available to you from that point on. You can't pick and choose single songs, you have to take all or nothing from each album you select.
