How to add tier prices in the product list

Inside the app/design/frontend/{interface}/{theme}/template/catalog/product/list.phtml add this inside the foreach loops for grid and/or list

<?php $this->setProduct(Mage::getModel('catalog/product')->setStoreId(Mage::app()->getStore()->getId())->load($_product->getId()))?>
<?php echo $this->getTierPriceHtml() ?> 

It does not look nice for grid but it can be fixed by css.
