Welcome to CDFreaks. Before I answer your question, is there anyway that your name has anything to do with the Smurfs? I noticed that if you take the 's' from the end of your name and put it at the beginning, you would be 'smurf4'. Juat curious...
As for downloading services, I am not sure if etree is a legal service, but as far as I know, it is free. This service mainly has 'Jam Bands' though, and may not be in your interest. Some good paying sites for you to use would include iTunes, Rhapsody, Napster. There are many more paying sites, but unfortunately, all those that I have listed do not include movie clips and games. Maybe somebody else here knows of a legal site that I don't?
For games and movies, you might have to look elsewhere.
Hope this helps.
One thing I failed to mention is that sites like those that I have mentioned include DRM [(Digital Rights Management), with the exception of etree.org] with the songs that you download, something not in the interest of most of us.
