Magnatune

Magnatune (via Doug Kaye, previous post), from their webpage:

We're a record label. But we're not evil.
We call it "try before you buy." It's the shareware model applied to music. Listen to 326 complete MP3 albums we've picked (not 30 second snippets).
We let the music sell itself, because we think that's the best way to get you excited by it.
Our selection is intentionally small: we never waste your time with mediocre music.
If you like what you hear, download an album for as little as $5 (you pick the price), or buy a real CD, or license our music for commercial use.
Artists keep half of every purchase. And unlike most record labels, our artists keep all the rights to their music.
No major label connections and no venture capital.
We are not evil.

I only found it less than 30 minutes ago and I've already decided to purchase an album (as soon as I get myself a credit card). The album in question is Ehren Starks - The Depths of a Year and I'm listening to it as I type this. After thinking for a while about it, I'm going with the physical CD, I think the security and the options (rip it yourself, play it in a normal stereo without mp3 support - like the one currently in my car) are worth the extra ~$8 USD.
Final remark: Magnatune is a good idea, a good site and a good service.
