I tried xolox for the first time last night.
Each song I downloaded is not a song at all.
It is a file that directs me to a porn site.
What can I do to correct this?

avoid files with !! in the begining and words like set up. These are sure fire signs that these files are bogus.

First off, keep everything up to date.. use windowsupdate.com to get IE security patches and keep a good virus scanner. A free online scan can be done at http://housecall.antivirus.com

Secondly, never get a file with an extension of .url, .htm, .html, .js, .vbs, .vb. Watch for the common spam files -- usually very small and return with a quote from your search..

Fakes I see a lot ::
!!--!! something
!! something
!!! something
!! Free! - something
Free -- something --
