See that's the thing about free and viruses either pay w/o virus or don't pay for a risk. Uh for now you can hear at least the song, if you can't like you heard on radio go here:
http://searchbeta.playlist.com/tracks#hollywood%20whore
but why don't you just download it from limewire/frostwire it's not that bad with audio files, there's almost no viruses. You could have an "On Access" Anti-Virus like Avira AntiVir
http://www.download.com/Avira-AntiVir-Personal-Free-Antivirus/3000-2239_4-10322935.html?tag=mncol
it searches everywhere you browse so when you downloading something from limewire/frostwire it detects it immediately.
There's also something like that but can convert a video into another format or that video into mp3 file it's great it works for me. All you do is go to youtube and search for it and inset the url into its box and choose your folder where you want it and done! It has an online based converter or the program that you install. If the internet one does not work the installer will.
Here, its called Vixy, here's the website an there's more information there.
