is this like grokster? also, can you download a song to your computer, if it's liscensed, and then delete it? only download to listen? don't understand if copyright infringement is downloading or uploading, someone help please, dont think is worth it if can get in trouble, would rather buy some songs every week instead of all that. also, if you find songs you want to keep, how do you buy the liscense, or can you even do that, and where send the money to? thanks again. sheila
