This is totally awesome:

For this summer's 25th anniversary of Prince's classic movie and album Purple Rain, SPIN is excited to announce the release of Purplish Rain, a tribute album made up of nine tracks commissioned by the editors of SPIN.

One very special note: Among the nine songs is a version of "When Doves Cry" performed by the Twilight Singers, featuring Apollonia, who costarred with Prince in the movie, and Greg Dulli -- check out SPIN.com's exclusive stream of the track!

The downloadable album looks to be much better than most storebought tribute discs, with Prince covers from Craig Wedren, Of Montreal and the Riverboat Gamblers. And, it's free -- all that's needed for download is a clue from the magazine.
