In these days of stuff being shoved on the internet for free both legally and illegally, a lot of people just download rather than buying physical music any more. This is something I'm not too happy about, but that's another story.
These days, there's a wealth of free, perfectly legal music on the internet (and elsewhere) if you look hard enough. What are some of the gems that you've found completely legal? Discounting the obvious Radiohead and Nine Inch Nails, of course.
The label Matador - who house Pavement, Mogwai and others - have something like 100 free MP3s from their various artists on their website.
Q magazine regularly give away free CDs, which I've taken shameless advantage of, getting, for example, the one Libertines song I want to own. I also discovered Nick Cave and Wilco via these CDs, both of whom are now among my favourite bands (and the latter of which are renowned for streaming their stuff on their webpage before it comes out).
What free delights have you found on the internet?
