www.emusic.com claims that you can have 25 free downloads. Are they really free? What's the catch?

Answer 1

The catch is that in order to get the 25 free downloads you have to sign up (which includes providing payment information) for their service. They count on you forgetting to cancel your membership before the trial period is over. Which is when the automatic re-occurring charges to your credit card/checking account are made.
The cancellation information is spelled out to you just one time and after that it is buried deep into the website.
If you want to take advantage of this type of offer, make sure you save the cancellation info and deadline so that you can avoid any charges
