It is always about the music.  Whenever I loved a group I went deep in their albums.  I never collected just to collect.  Although sometimes the first album of a group or artist I bought was excellent and subsequent albums never matched up.  I do read music reviews.  My collection is out of control since I married my second wife.  She “discovered” E Bay and went a little crazy for awhile.  Now there is music in my house I am not familiar with or have no interest in.  Like when she bought the complete set of Emerson, Lake and Palmer.  I had stopped listening to them after their second album.  I am glad she is no longer doing that. I now do have some music I never thought I would ever see again.  In my first marriage I had to make room to include some music which meant I had to get rid of some of the “deadwood” in my collection.  In my new house I have more room so I can collect more music.  There is always an interesting piece of music I have not heard before.
