Maybe I ought to just shut up. Despite telling readers that Apple's (NASDAQ:AAPL) stock split was meaningless and that the shares were overvalued even for a Rule Breaker like me, the stock has continued to go up, up, up. What the heck is going on?

Well, at the risk of earning an undisputed claim to the title "master of the obvious," the answer is this: Apple continues to perform in every area of its business. Witness yesterday's announcement that the iTunes Music Store has passed 300 million downloads and now boasts a library of more than 1 million songs. New artists making music available through iTunes include the Grateful Dead.

Indeed, it seems Apple's latest innovations have become cultural icons, none more so than the many flavors of the iPod. The Mac maker has reportedly sold more than 10 million of the digital music players. Think about that. As of yesterday, only 30 songs had been downloaded for every iPod owner out there.

But the pace appears to be picking up: Apple reported 200 million downloads on Dec. 16. That's 75 days to add 100 million songs, or 1.3 million downloads per day. It took Apple 156 days to go from 100 million to 200 million downloads, or a rate of 641,000 downloads per day. Though these are nothing more than estimates it does appear that Apple has doubled its rate of daily music downloads in a little more than six months. That may be because many consider the iPod to be a lifestyle as well as a music player. Heck, we even have a discussion board here at dedicated to just such a group of folks.

At some point Apple's hits are bound to stop, but can anyone really predict when that will be? Nope. So, at least for now, I'm done trying.
