I would suggest that your perception changes - which is a good thing because otherwise you'd never have got past the first record you ever bought! It's the nature of art, and popular music reflects this perfectly, that we desire constant change. Although you may develop favourite songs, or albums, based on the events that occurred when you first heard them, it is the nature of the enjoyment of music to look for new stimulation, which ideally co-exists with your past choices. Yes, I still love my Beatles and Pink Floyd albums, but I couldn't wait to get home with the Dandy Warhols album today. Music moves along constantly, and I for one am forever glad that it does. I don't think 'familiar' is the same as 'dull' what does everyone else think?
