OK, almost free. To get a free mp3 of “The Rake’s Song” (album, The Hazards of Love, due March 24) you do have to give up their email address. I guess if you can’t get cash for your music, you might as well as pester the hell out of cheap listeners worldwide with notices for Crane Wife Activewear clearance sales. I’ll all for it. As for the single, well, it’s not nearly as warm as an “O Valencia” hoodie. But, hey, it’s (almost) free.
