I think the first mix tape I made was for myself; maybe some Pearl Jam and Led Zeppelin I'd jog to. Then I found out girls liked mix tapes and I started making them with different songs -- each carefully chosen to represent something.

Now it's not just teenagers in love who make playlists in iTunes. Really, these are not songs but lists -- lists that call individual songs from one's harddrive. And it's the individual song that people purchase (or don't purchase) today. Playlists can have hundreds of songs and there can be overlap from one playlist to another. In fact, they can even be random or "smart" -- not pre-set, but based on attributes such as how often songs are listened too, how highly they're ranked, their genre, etc.

But where does all this wizardry leave the 14-song CD sitting at the counter in Starbucks? Given the context of 99 cent songs at the iTunes store, infinite playlists and zero-loss digital copying, I think of that CD as just another playlist.

Like Sheryl Crow just made me a mix tape.

Ever dug into iTunes with a tune in your head, only to find you can't buy it on iTunes?

Ever used iTunes like an LP player ... one song at a time?

YouTube is basically a P2P music service, with every song I've ever wanted to hear in video format. Content owners likely allow YouTube to host music videos for the same reason they let radio play songs. But if they knew I used YouTube like a kind of infinite LP player, maybe they wouldn't.

This is to the Internet what "The Making of the President" was to the making of the President (after 1960).

FTA: "Hit-driven economics is a creation of an age without enough room to carry everything for everybody.... Consider the implication: If the Amazon statistics are any guide, the market for books that are not even sold in the average bookstore is larger than the market for those that are ... In other words, the potential book market may be twice as big as it appears to be, if only we can get over the economics of scarcity. ). "
