Apple's iTunes works with any mp3 player, not just iPod. It'll even work with your mobile phone. The iTunes software is free, and users can download one free song each week. You don't get to choose the song though. It's more of a 'Single of the Week' kind of deal where they pick a new release and give it to anyone that wants it.

iTunes songs cost either 79p or 99p, but despite the fact that this free offer is worth over £40 a year, I'll stick it in the 'Under a Tenner' category.
