I ripped The Wall without VBR tags, as required by lame --nogap at the time. This means the tracks have the wrong length in the player.

The seek tool seems to remember its maps for those tracks that under-report their time (truncated to the believed time, I think), but forgets all those for tracks that appear longer than they are.

As a wishlist, WIBNI the correct length (even better a full VBR header) was calculated as part of the seek tool mapping, and applied to the database at the next sync?
