never heard of the band Wilco, but apparently they sent out a press release a while back about their new album, which contained the following part.

We also have our usual guilt abatement plan for downloaders. If you have downloaded the record, we suggest you make a donation to one of the band's favorite charities, the Inspiration Corporation -- an organization we've supported in the past & who are doing great work in the city of Chicago. Information and donation button here: http://inspirationcorp.org/.

Not sure how many people who downloaded the album are going to do this, but it is a very cool idea.
