Whenever I click on a link to download any song , it does not get downloaded it starts playing on VLC media player. I have changed my tool option in mozilla Firefox to always ask but still no effect. The songs still keep playing irrespective of the site.

Right click "save file as"

The file gets saved as a php file. I have to convert it into a mp3 file. Is there no way to prevent this.

Sounds like the ONLY option you have available is to STREAM rather than download..

Dose sound like a stream link

This problem only happened after I installed vlc 2.0.1
