Steve Jobs and Co. can all give each another a pat on the back for what is a significant milestone in online music sales. Apple sold their 3 billionth song (wow) through the iTunes service and don't look to be slowing down any time soon.

This makes Apple the 3rd largest music distributor (trailing WalMart and BestBuy physical stores) and accounts for 10% of all US music sales alone, out shining Amazon (6.7%) .

The iPod certainly played a huge part on the online store's success, for without it iTunes would just be another regular online music store. A monumental effort non the less.
