If you only care about sound quality then digital music is a superior format. I prefer CDs over sound files since it is more fun to pick from a catalog of CDs on the shelf then a list of artists on a display.

That said, if you care about the album or the art vinyl records are superior. A CD has very limited visuals and seeing it disappear into the machine feels disengaging (although it is handy not to have to turn a CD over half way through).

Also old vinyl is really cheap and plentiful. You can go to the thrift store and buy and old Beatles album for half a dollar. It is really easy to start a collection from old cheap records. Old CDs only go back so far and it’s hard to find good CDs among all the trash in the thrift store. I usually have to go to the record store and buy a good used CD for $10 a piece (which I do, but not as often as a thrift store record). Meaning that casual lovers of music that don’t like to spend too much money probably have a greater vinyl collection then CD collection (although they probably have an even greater mp3 collection).
