Here's a nice feature in iTunes 7.0 -- click on the Album column to sort by album (as you would expect), then click again to sort by 'Album by Artist' and again for 'Album by Year.' Definitely a nice sorting option for those like me who like to play whole albums at a time, but want to keep artists together.
