Fair enough

Well I do put it in, I just don't sort songs mentally by date. By genre, yes; even by mood; but I see nothing incongruous in having an early Zappa, followed by a recent Silverchair for example.

I think if I was searching for a song I would always do it by title or artist, as I wouldn't know when the song came out anyway.

Of course, I am renowned (amongst siblings and friends) for not even knowing what year/month/week/day it currently is until I look at my watch or PC clock as it doesn't really affect me.
