Thanks Tim Sneath, for pointing to Magnatune. Magnatune is a record-label, that applies the shareware principle to music. You can listen to all tracks from the albums (almost 400) they have in store, in MP3 format. If you decide you like it, you can buy an entire album for as little as US$5 or 4. You can always pay more, but you don’t have to. Half of what you pay goes directly to the artist.
After you have paid, you will be pointed to specific download locations, where you can download the music in lossless (WAV, FLAC, etc) format, so when you burn it on CD for normal audio-playback, you have the same quality as when buying the “normal” album in a recordstore. Very cool stuff.
If you want to broadcast the music they have, you can also buy a commercial license.
