Downloading and validating MP3 from URL

[eluser]Sire[/eluser]
Yes, getid3 library will give much more information about the mp3.

However, fileinfo_file will still tell you if the mp3 is valid. It reads the file, much like the 'file' command on your server and /usr/share/file/magic.mime. It doesn't just use the file extension it looks into the headers of the file. It isn't reading the web headers, which can be faked.
