It's a natural fit. These are not replacements for people buying individual songs or albums. But they're great for well-established artists with a fan base behind them that wants more product.

We have tracks that are temporarily exclusive to us in the Music Store, and so do most of the other services.

We are taking advantage of the medium. This is the stuff that you can only do in digital music.

People know me for up-tempo songs because of my hits.

All I wanted to do was write songs, but all the things I wrote in Detroit, they put them out by different artists.

It's not quite done. I'm hoping to finish the last of the songs while I'm down (in South America). I'm bringing my tape machines and all that down. If I can come back and finish the last few songs in January, then it will be out in April or something.
