Posing as music from famous stars, they in fact contain a monotone voice asking the listener to invest in an obscure Canadian company.
The MP3 files are being widely spammed in e-mails that often contain no subject line or message body, net security firm Sophos reports. Some of the filenames used include hurricanechris.mp3, allforone.mp3, carrieunderwood.mp3, elvis.mp3, baby.mp3, fergie.mp3, and bbrown.mp3.
The female (apparently British) voice on the MP3 file, recorded at low bit-rate and randomly altered to avoid detection by anti-spam filters, seeks to attract interest in Exit Only, a Canadian firm that runs a Web site marketplace for new and used motors.
If you are curious, or are a closet spam-lover, you can have a listen at a 30-second snipper from Sophos here.
