Radiohead has a new album coming out called In Rainbows. It's only available from their site for now, either as a download (released Oct 10) or as a "discbox" that includes the CD, a bonus CD, two records, and assorted photos, books, etc. (released Dec 3). (via rex)
Update: Also, Radiohead is letting the buyer choose his/own price for the online album. This has been done before, notably by Magnatune, who offers albums for between $5 and $18 with a recommended price of $8...and people often pay more than the recommended. (thx, greg)
Update: Singer Jane Siberry does variable pricing for her music as well. Siberry also cleverly lists what other people are paying (currently $1.18 per song, a bit more than the recommended $0.99). Freakonomics explains. (thx, phil)
