Pop music blog Chart Rigger has tipped us off to a free download of Ke$ha's new single We R Who We R. The single will be available until noon tomorrow and requires that you add your email address to Ke$ha's mailing list.
The single is a 160 kbps MP3 that does not come with artwork. So, you will have to snag the cover from the AAX gallery if you want artwork for the music file. The file isn't tagged either. Oh, well. You get what you pay for, right?
