The eMusic offer is solid. Here is another solid one I just found via cystsfts. Basically, go here and sign up for one of the offers (I did/suggest the Realplayer-trial one). Next use the referral code and pass along to your friends. If you are like me, your iPod is two years old with shit battery life. Get a brand spankin’ new one. Click here.
