Ok, this is the case!

I have a winamp stat, it read the *.mp3 name...

But I need a stat that read's the TAG..

So, do anybody have or know about a nice amp stat?

Please, I get so [censored] annoyed by the one I use now!! Thanks!!

All you need to read the ID3 tags of an MP3 file is the $sound identifier.

wanna help me?

/help $sound

Example:

//echo -a $sound(filename.mp3).title

but who shold that read from winamp?

What I'm trying to tell you is that you don't need to read from Winamp to get the MP3 information, all you need is the filename and the $sound identifier and you'll be able to turn all of the following details:
album, title, artist, year, comment, genre, track, length, version, bitrate, vbr, sample, mode, copyright, private, crc

If you insist on having the information sent by Winamp, there are several addons for both Winamp 2.x and 3 which will use DDE to send a message to mIRC whenever a song is played, as well as numerous DLLs for controlling Winamp and returning information, amp_in.dll for example.
