Burn your music to cd's, delete the files and free up the space... and play them with the cd drive on the computer. It is only one more step...put the cd in and hit play. You have to remember here, by leaving all that on the computer you have very little space remaining and therefore you ARE running the risk of a hard drive crash and then the chances are you would lose it all anyway. If the thing crashes and you have to reformat you can't get that stuff back, except download again.
