google Bit Torrent software ... download one of them (Azureus / UTorrent are what I use) and then use something like "piratebay.com" to find torrents ... dead simple when you get the hang of it ... which is not hard ... but you will need broadband ...
Limewire is the best download site for single songs i've ever tried. Just click on the link below and press download. p.s. any time you turn it on, it'll ask if you want to upgrade to pro, just click later.
