If you're a college student, you absolutely must sign up for Ruckus.
Here's the deal: it's completely free to sign up and you can download as much music as you like (They have just about everything!) for free.
The catch? You can't burn stuff onto CDs or iPods etc. But if you're cool with listening to music on your computer, this is definitely the way to go.
You need a college email address to sign up but pssst: if you have kids or friends in college, you may be able to talk them into lending you their log-in information.
Free music for college students!
