Well, how's this for 'aging' myself:  late 50s Rock &amp; Roll, Beach Boys, Jimmy Buffet, Alan Jackson, George Strait &amp; George Jones +  most classical, opera &amp; good jazz.  Quite an eclectic mix.  I can be listening to the London Symphony on minute &amp; George Jones the next.  Just about anything except hard rock, acid rock, &amp; rap/hiphop.
