I do not share all my freebies here, but this one is different than most. I think some might like this!

Music Lab is a research project conducted by scientists from Columbia University to learn about how people form opinions about music. If you participate in Music Lab you will have a chance to download free new music.

After answering a few questions about yourself, you will be presented with a menu of songs by cool new artists. Your participation will take between 5 minutes and about two hours depending on how many songs you choose to listen to.
