I guess most people don't see this as there empegs are pretty static - me I'm a newbie and still have a lot of work to do not least because I created my collection back before ID3 was supported by ripping programs. I would re-rip except I rip tracks and not albums and it took weeks last time to identify what to rip. Guess I'm fussy about what I listen too :-)
