New Free Music Service with a 30-day "hitch"

There is a new online music service that is delivering music and video content for FREE, however, you are obligated to view their website (and their advertising) on a regular basis in order to keep the music playable.

As quoted from the SpiralFrog website:

How come there's no cost – what's the catch?
SpiralFrog is an ad-supported Web site. We sell ads on our pages to advertisers who want to talk to you. And we give the majority of that advertising revenue to the music publishers and labels who own the music you're downloading.
Most of our song and video downloads take a short, consistent amount of time to complete, during which we encourage you to keep discovering new areas of the Web site. Every page you visit allows us to serve more advertising, thus building the revenues we can pay to the content creators.
We do NOT ask you for a credit card. But we do ask for your time and attention. And, for that, we thank you…

You are required to log in every 30-days to keep your account active, and there are currently no limits to the number of songs you can download. If you fail to renew your membership every 30 days - your files become inaccessible after a total of 61 days. And -- SpiralFrog is sharing advertising revenues with music publishers -- so everyone wins (advertisers get verified exposure, publishers and musicians get paid, and users get free music and video).

This is a great concept that is likely to catch on with users.
