For anyone who plays on Beta 1.3-1.7 on 360 or PC, if you want the greatest seed, use cereal
There's pumpkins, trees, sugar, sand, clay, flowers, and many caves, shallow and deep, near the spawn. One cave, over a hill leading to desert mountains, has plenty of coal and is ideal for building a house in. I have found 16 spawners in the seed, two of which are in the deep cave next to the spawn. I found both music discs. There is plenty of visible iron, coal, redstone, and gold in the caves. If you break down one of the dungeon walls in the cave next to the spawn, the one with chests, you will find diamonds, lapis and coal. Email me at firstname.lastname@example.org
for coordinates. I have no pictures, sorry
Oh, and I found underground plants. The seed has many oddities.
