Thought on Buying MP3s

I am probably one of those dinosaurs who still buy classical music CDs. However, lately I found I bought more and more MP3s. Why? Well, no place to shop is one reason (I miss Tower Record). The other is there are more and more choices for MP3s now. I found I would get MP3s if

- it is harpsichord (perfect for MP3 recording)
- it is historical recording (recording quality is bad already, no need to get CD)
- it's period instruments (for period instruments before 19th century, no need to get CD)
- it's performed by someone I hadn't heard of (I discovered many good performers this way)
- it's experimental music (most of my Philip Glass collection stays in MP3 forever)
- it's vocal work (human voice doesn't need much bandwidth)
- it's free (duh)

I will get CDs if
- it's Symphony, especially if it's a Mahler Symphony
- I know I will lend it to somebody

Judging from the list, I wonder if soon the day will come that I don't buy any CDs any more. I shudder when I think about it.
