Recognising fake/spam files helps. Virus thread: Typical virus spam file sizes - Make a note of them (click on blue link to see) & also How to find music.

I'd also suggest you first check songs by playing them with VLC - (click on link) which will play both audio & video files. VLC will not allow url's inside the file to force it to any virus ridden website.

BTW you did not specify which version of LW you are using.
