You can put all the Cds you own into Itunes and syncronize your ipod. I have small Ipod and never spent a penny on music. Just used my CDs. A few years back Pepsi had a promotion in which you saved 5 bottle caps for one song. A friend of mine has a redemption center and saved my son all her caps and he got tons of free music that way. Even the custodians at work were leaving pepsi cps on my desk at night. There are many applications that are very useful and free, like measurements conversions, e-mail, etc.
